5 Reasons To Wear Sunglasses In The Fall

When we think of fall accessories, the first things that come to mind are warm sweaters, plush scarves, or a snug pair of boots. Here’s another essential item to add to your list: a good quality pair of UV-blocking sunglasses.

But why is it so important to protect your eyes when the sun seems to be hiding behind clouds on most days? While it may not make much sense, you’ll get a better understanding by the time you finish reading this article. So let’s dive in and explore the 5 reasons you should protect your eyes from the sun in the fall.

Sunglasses: Summer Vs. Fall

The Sun’s Position

While we may squint more in the summer, the sunlight’s path to the eyes is more direct in the fall as the sun sits closer to the horizon. This places our eyes at greater risk of overexposure to UV rays.

Changing Temperatures

Irritating symptoms like dry, red, or watery eyes are often due to the season’s cool and harsh winds. The colder the air, the stiffer and thicker the eyes’ tear oils (meibum) become. Because thicker meibum doesn’t spread as evenly over the surface of the eyes, the tears can’t offer sufficient protection and moisture.

Minimize irritation by shielding the eyes from cool winds with wraparound sunglasses.

Many eye diseases can be quickly and easily diagnosed during a comprehensive eye exam. If you were diagnosed with an eye disease, such as Cataracts, Glaucoma, Macular degeneration, Diabetic retinopathy, or Dry eye, you may be overwhelmed by the diagnosis and confused about what happens next. Will you need medications or surgery – now or in the future? Our Fairfax eye doctor has prepared the following answers to your questions about eye disease.

UV Rays

Exposing your eyes to the sun’s harmful ultraviolet (UV) rays is problematic year-round, as it can result in serious eye diseases, such as cataracts and macular degeneration. That’s why it’s important to wear 100% UV-blocking sunglasses anytime you’re outdoors, no matter the season.

Make sure to sport your sunnies even on cloudy days, as up to 90% of UV rays pass through clouds. Furthermore, outdoor objects like concrete and snow reflect a significant amount of UV rays into the eyes.

Fall’s Dangerous Sun Glare

Because the sun is positioned at a lower angle in the fall, it can produce a brutal glare that poses a danger for driving. Rays of light that reflect off of smooth surfaces like the metal of nearby cars can be so bright to the point of blinding the driver.

You can combat this dangerous glare by wearing polarized sunglasses. These lenses reduce the glare’s harmful effects by filtering out horizontal light waves, such as the ones reflected by a shiny car bumper.

6 Crazy Holiday Eye Injuries to Avoid

As the season to deck the halls arrives, make sure that you aren’t one of the many people who find themselves celebrating in the urgent care clinic due to an eye injury. The holidays present many opportunities for potential eye injury so it’s important to be aware and proceed with caution. Here are some common eye accidents waiting to happen and tips to avoid them so you can be prepared and enjoy your holidays to the fullest!

  1. An eye-full of pine

    Many accidents occur when proper care is not taken in putting up and decorating the Christmas tree. First of all, if you are cutting down your own tree, make sure you are wearing proper eye protection both when cutting and when loading your tree onto your car. If you are buying a tree, be extra careful when untying it as branches can pop out rather fast – a definite danger to your eyes! It’s best to wear glasses or goggles during the entire process of handling the tree. And don’t forget to be careful when you are decorating! All you need is a wobbly ladder or an unsteady tree stand to cause a tumble into the sharp, prickly pine needles. Not to mention, sharp ornaments can pose a danger to the eyes as well.

  2. The spray snow slip-up

    Spray snow can be a beautiful and festive addition to your tree decorations but be careful that you are always pointing it in the right direction. Make sure the spray you purchase is nontoxic and wear safety goggles when spraying to avoid an accidental spray to the eye. Be wary of those aerosol string cans as well.

  3. Champagne cork projectile

    Watch out for that bubbly! When opening a champagne bottle always point it away from anyone or anything breakable just in case it shoots off. That flying cork can cause a serious bruise or an eye injury if you aren’t careful.

  4. You’ll shoot an eye out!

    Just like the famous movie quote predicted, toy guns and projectiles can be a tremendous danger to the eye, causing almost 20% of eye injuries during the holiday season. Nerf guns, darts (even foam darts), slingshots, water guns and any kind of shooting device, no matter how soft the ammunition, can cause serious eye damage when shot directly into the eye. Be wary of lasers as well and make sure that any laser products comply with the national regulations. Lasers and very bright lights can cause retinal damage if pointed directly at the eye. If you do decide to purchase such a toy for a child that is old enough and mature enough to be responsible, consider buying proper eye protection to go along with the gift.

    Avoid purchasing any toys or gifts that have sharp, protruding parts and make sure that any potentially hazardous toys are played with under adult supervision. When purchasing gifts, if you are uncertain about the safety of a certain toy, check out W.A.T.C.H. (World Against Toys Causing Harm) or other organizations that give advice about specific toy safety.

  5. Dangerous dress up

    Got a holiday party on the horizon? While you may be tempted to add a pair of cosmetic contact lenses to your ensemble, make sure they are fit properly and purchased by a licensed eye doctor. Improperly fit lenses or lenses made of sub par materials can cause serious complications such as a corneal abrasion or infection.

  6. Sunburned eyes

    If your holiday time includes a chance to play in the snow or ice, make sure you have your sunglasses ready. UV light reflects off snow and ice increasing the risk of sunburned eyes and potential long term damage. Winter sunwear is just as important as it is during summer fun in the sun.

If you approach the holidays with the eyes on your mind, you can stay safe and avoid potential injury that could put a damper on your festivities.

Is Your Teen Ready for Contacts?

Many teens who wear glasses are eager to try out contact lenses for convenience, fashion or to just provide another option for vision correction. For teens who feel self-conscious in their glasses, contact lenses can be a way to improve self-esteem. Young athletes and swimmers find that contacts are an excellent option for sports, especially as younger kids are becoming involved in travel sports and club teams outside of school.

While contacts might appear to be the perfect solution for teens that need corrective eyewear, they are a convenience that comes with a lot of responsibility so it’s not a decision to take lightly. Improper use of contact lenses can cause severe discomfort, infections, irritation and, in the worst cases, eye damage or even permanent vision loss.

“With Privilege Comes Responsibility”

Contact lenses are a medical device and should always be treated as such. They should never be obtained without a valid contact lens prescription from an eye doctor, and always purchased from an authorized seller. Among other issues, poor fitting contact lenses bought from illegitimate sources have been known to cause micro-abrasions to the eyes that can increase the risk of eye infection and corneal ulcers in worst case scenarios.

Particularly when it comes to kids and teens, it is best to purchase contact lenses from an eye doctor as they possess the expertise to properly fit contact lenses based on the shape of the eye, the prescription, the lifestyle of the child and other factors that may influence the comfort, health and convenience of contact lens use.

There is some debate over the recommended age for kids to start considering contact lenses. While some experts will say the ideal age is between 11 and 14, there are many responsible children as young as 8 or even younger who have begun to successfully use them. When children are motivated and responsible, and parents are able to ensure follow-up to the daily regimen, earlier contact lens use can be a success. A good measure of whether your child is responsible enough to use contacts is whether they are able to keep their room clean, or maintain basic hygiene like brushing teeth regularly and effectively.

When you think your child might be ready, you should schedule an appointment with your eye doctor for a contact lens exam and fitting. The process will take a few visits to perform the exam, complete a training session on how to insert, remove and care for lenses, then to try out the lenses at home and finally reassess the comfort and fit of the contacts. You may try out a few varieties before you find the best fit.

What Kind of Contact Lens Is Best for My Teen?

The good news is that contact lens use has become easier than ever, with safety, health and convenience being more accessible as technology improves. There are a number of options including the material used to make the lenses (soft or rigid gas permeable), the replacement schedule (if disposable, how often you replace the pair – daily, weekly, biweekly or monthly) and the wear schedule (daily or extended overnight wear).

Single use, daily disposable lenses have become very popular, particularly with younger users, because they are easy to use, requiring no cleaning or storing, and therefore they reduce the risk of infection and misuse. You simply throw out the lenses at night and open a new one in the morning. Your eye doctor will be able to help you and your teen determine the best option.

Tips for Contact Lens Wearers

Following are some basic contact lens safety tips. If your teen is responsible enough to follow these guidelines, he or she may be ready for contact lens use:

  1. Always follow the wearing schedule prescribed by your doctor.
  2. Always wash your hands with soap before applying or removing contact lenses.
  3. Never use any substance other than contact lens rinse or solution to clean contacts (even tap water is a no-no).
  4. Never reuse contact lens solution
  5. Follow the eye doctor’s advice about swimming or showering in your lenses
  6. Always remove your lenses if they are bothering you or causing irritation.
  7. Never sleep in your lenses unless they are extended wear.
  8. Never use any contact lenses that were not acquired with a prescription at an authorized source. Never purchase cosmetic lenses without a prescription!

Contact lens use is an ongoing process. As a child grows, the lens fit may change as well, so it is important to have annual contact lens assessments. Plus, new technology is always being developed to improve comfort and quality of contact lenses.

Contact lenses are a wonderful invention but they must be used with proper care. Before you let your teen take the plunge into contact lens use, make sure you review the dangers and safety guidelines.

Inside a Life With Color Vision Deficiency

What’s it like to be color blind? Contrary to what the name implies, color blindness usually does not actually mean that you don’t see any color, but rather that you have difficulty perceiving or distinguishing between certain colors. This is why many prefer the term color vision deficiency or CVD to describe the condition. CVD affects men more than women, appearing in approximately 8% of men (1 in 12) and .5% of women (1 in 200) worldwide.

Having color vision deficiency means that you perceive color in a more limited way than those with normal color vision. This ranges from mild, in which you may not even be aware that you are experiencing color differently, to severe, which is perhaps the more appropriate from to be called “color blind” and involves the inability to see certain colors.

CVD can be inherited; it is caused by abnormalities in the genes that produce photopigments located in the cone cells in your eyes. The eyes contain different cone cells that fire in response to a specific color, blue, green or red and together allow you to see the depth and range of colors that the normal eye can see. The type of color blindness and therefore the type of color vision that is impaired, is based on which photopigments are abnormal. The most common form of CVD is red-green, followed by blue-yellow. Total color blindness or the complete inability to perceive color is quite rare. About 7% of males have congenital color blindness that they inherit from the mother’s X-chromosome.

Color blindness can also be the result of eye damage, specifically to the optic nerve, or to the area in the brain that processes color. Sometimes an eye disease, such as cataracts, can also impact one’s ability to perceive color. Systemic diseases such as diabetes or multiple sclerosis can also cause acquired CVD.

Living with CVD

Red-green color blindness does not mean only that you can’t tell the difference between red and green, but rather that any color that has some red or green (such as purple, orange, brown, pink, some shades of gray, etc) in it is affected.

You many not realize all of the ways you use even subtle distinctions in color in your daily life. Here are some examples of ways that CVD can impact your life and make seemingly everyday tasks challenging:

  • You may not be able to cook meat to the desired temperature based on color.
  • Most of the colors in a box of crayons will be indistinguishable.
  • You may not be able to distinguish between red and green LED displays on electronic devices that indicate power on and off.
  • You may not be able to tell between a ripe and unripe fruit or vegetable such as bananas (green vs. yellow) or tomatoes (red vs green).
  • Chocolate sauce, barbecue sauce and ketchup may all look the same.
  • Bright green vegetables can look unappealing as they appear greenish, brown or grey.
  • You may not be able to distinguish color coded pie charts or graphs (which can cause difficulty in school or work).
  • Selecting an outfit that matches can be difficult.

Knowing that one is color blind is important for some occupations that require good color discrimination such as the police officers, railway workers, pilots, electricians etc. These are just a few of the ways that CVD can impact one’s daily life. So is there a cure? Not yet.

While there is no cure for CVD, there is research being done into gene therapies and in the meantime there are corrective devices available including color vision glasses (such as the Enchroma brand) and color filtering contacts that for some can help to enhance color for some people. If you think you might have CVD, your optometrist can perform some tests to diagnose it or rule it out. If you have CVD, you can speak to your eye doctor about options that might be able to help you experience your world in full color.

Bifocal and Multifocal Contact Lenses

If you are over 40 and have difficulty seeing close up, you probably have a common age-related condition called presbyopia which is when the eye’s natural lens loses the ability to focus on close objects. Presbyopia is a natural process that occurs as the eye ages and affects the majority of people from age 40 and upward. Individuals with presbyopia are often familiar with the need to hold reading materials such as newspapers an arm’s length away from their eyes in order to see clearly, yet reading glasses with bifocal or multifocal (such as progressive) lenses can help.  

Fortunately for those who don’t like the look, feel or inconvenience of reading glasses, there is another option. Bifocal and multifocal lenses are also available in contact lenses in both soft and Rigid Gas Permeable (RGP) varieties.    

Multifocal contact lenses give you added freedom over glasses and they allow you to be able to view any direction – up, down and to the sides – with similar vision. People wearing progressive lenses in glasses on the other hand have to look over their glasses if they want to view upwards or into the distance.

Multifocal contact lenses are generally designed in one of two ways, as either simultaneous vision lenses or alternating vision lenses.

Simultaneous Vision Lenses 

The most popular version of multifocal contact lenses, simultaneous vision lenses present the distance and near vision zones of the lens at the same time. Typically after a short adjustment period your eyes learn to utilize the segment of the lens that they need to focus on the desired object and essentially ignore the other. 

Translating or Alternating Vision lenses

Similar to bifocal eyeglass lenses, these contacts are divided into distinct areas or zones and your pupil will move to the desired zone depending on your vision needs. Typically the top of the lens, which is what you look through when looking straight ahead is for distance vision and the bottom area (what you look through when you look down) is for near vision. However, this can be reversed according to unique vision needs. 

An Alternative Option to Multifocal Contact Lenses: Monovision

Monovision is another contact lens alternative for presbyopia particularly if you are having difficulty adapting to multifocal lenses.  Monovision splits your distance and near vision between your eyes, using your dominant eye for distance vision and your non-dominant  eye for near vision. 

Typically you will use single vision lenses in each eye however sometimes the dominant eye will use a single vision lens while a multifocal lens will be used in the other eye for intermediate and near vision. This is called modified monovision.  Your eye doctor will perform a test to determine which type of lens is best suited for each eye and optimal vision. 

Are Contact Lenses Right for You?

If you have presbyopia, contact lenses may be a great option for you. Many people prefer the look and convenience of contact lenses over traditional reading glasses. Speak to your eye doctor about the options available to you.

Workplace Eye Wellness: The Dangers of Blue Light

woman 20with 20laptop

When people think of workplace dangers to the eyes, it is usually machinery, chemicals or construction materials that come to mind.  However, a growing danger to the eyes is one that may be less obvious – exposure to blue light from digital devices, television and computer screens and artificial lighting.  

While the long-term effects of blue light or high-energy visible (HEV)  light emission are not yet fully known, what is known is that blue light is a cause of computer vision syndrome (CVS) and sleep disruptions.  60% of people spend more than 6 hours a day in front of a digital device and 70% of adults report some symptoms of computer vision syndrome (CVS) which include eyestrain, headaches, blurred or double vision, physical and mental fatigue, dry or watery eyes, difficulty focusing, sensitivity to light, or neck, shoulder or back pain (caused by compromised posture to adjust to vision difficulty). Most people do nothing to ease their discomfort from these symptoms because they are not aware of the cause. 

In its natural form, blue light from the sun is actually beneficial to your body by helping to regulate your natural sleep and wake cycles – also known as your circadian rhythm.  It can also boost your mood, alertness and overall feeling of well-being. However, prolonged exposure to artificial sources of blue light, such as that found in electronic devices, television and energy-efficient fluorescent and LED lights, has been shown to cause disruptions in the circadian rhythm as well as more serious vision problems. Researchers at Harvard University have linked blue light with damage to the retina at the back of your eyes, indicating that long-term exposure to blue light could be linked to age-related macular degeneration (AMD) and possibly other serious health and vision problems. 

Since 43% of adults work at jobs that require prolonged use of a computer, tablet or other digital monitor, blue light is an increasingly serious threat to your vision, health and productivity. There are a number of options for reducing your exposure to blue light which include computer glasses, specialized lenses and protective coatings. Speak to our eye care professionals to determine which option is best for you.

  • Single Vision Computer Glasses: Provide the optimum lens power and field of view for viewing your computer screen without straining or leaning in to reduce symptoms of CVS. These are ideal for when the computer is at a fixed working distance, and work well if the user needs to view multiple screens at the same working distance.
  • Office Lenses or Progressive Lenses: No-line multifocal eyewear that can be made to correct near, intermediate and some distance vision with a larger intermediate zone for computer vision if indicated. Perfect for those with presbyopia which is the gradual loss of focusing ability that occurs naturally with age. Office lenses work like progressive lenses but provide a wider field of view for intermediate (1-3 m) viewing distance and near working distance (about 40 cm). 
  • Blue-Blocking Lenses: Definitely recommended for this electronic age, blue-blocking lenses block blue light emitted from computer screens that is associated with glare, eye strain and possible sleep disturbances. 
  • Anti-glare and filtering coatings (treatments): Eliminate reflections from the surfaces of your lens to reduce eye strain and discomfort from glare. Some coatings can also block blue light emitted from computer screens. 

While all of these are good options for protecting your eyes, the 20/20/20 rule still applies – after every 20 minutes of near tasks, look at something beyond 20 feet away for at least 20 seconds…it’s a good time to stretch the rest of the body too. 

Additionally, diets high in lutein and zeaxanthin, which are carotenoids found in dark, leafy green vegetables like spinach and kale are protective to blue light damage.

A note about children and blue light:

Children are more prone to blue light damage than adults because the natural lenses in their eyes are so clear that blue light passes easily through to reach the retina.  Adults are somewhat less prone since the older we get our natural lenses become more cloudy and blue light does not pass through quite as easily. Pediatricians recommend that young children under the age of two should get ZERO screen time.   They have much better ways of developing their eyesight with activities requiring hand eye coordination with high contrast physical objects.

Technology is advancing the world, and our jobs and daily lives will only continue to rely upon it. Don’t let technology get in the way of your vision and your health. Ask us about the best solution for you. 

How to Find the Right Pair of Glasses for your Child

glassesondogs

Whether you are looking for regular prescription glasses, sunwear or protective sports eyewear, it can be tough choosing the best eyewear for children and teens. On the one hand, they need to be comfortable and provide the optimal fit for improved vision and protection. At the same time, they also need to be durable, especially if your child is active, plays contact sports or tends to drop or lose things. Not to mention, particularly once you get into tween and teenage years, they have to be stylish and look good. When you add in a budget and your child’s opinion, the decision can be truly overwhelming.

Before you begin looking, it is best to narrow down your options by answering the following questions (and consulting your eye doctor when necessary):

  1. Does my child need to wear his or her glasses all the time or are they for part time wear?
  2. Does my child’s prescription call for a thicker or wide lens requiring a certain type of frame?
  3. Does my child have any allergies to frame materials?
  4. What type of sports protection does my child need?
  5. Would cable (wrap around) temples or a strap be necessary for my child (particularly in toddlers)?
  6. Do I have a preference in material or features (such as flexible hinges or adjustable nose pads)?
  7. Are there particular colors or shapes that my child prefers or that will look most attractive?

Armed with the answers to those questions and a qualified optician, you can begin your search. Keep the following tips in mind:

  1. Including your children in the selection process will greatly enhance the chances of them actually being excited about wearing and caring for their glasses. So make it fun and exciting for them!
  2. Polycarbonate or Trivex lenses are impact-resistant lenses that are recommended for children’s eyewear to protect their eyes. Also consider adding a scratch resistant coating. 
  3. When trying on options, consult with the optician to ensure proper fit. Make sure the frames don’t slide off the bridge of the nose, cover the eyes, squeeze at the temples or extend too far behind the ears. Proper frame fit is especially important for kids with specialty prescriptions like bifocals or Myovision, and for kids with lazy eye (amblyopia) and high spectacle Rx.
  4. If shopping for protective sports eyewear, consider the conditions of the sport your child plays to ensure proper eye protection. They now have much more selection in children’s safety eyewear with cool designs and some glasses even have convertible temples (arms) and straps to become interchangeable dress wear and safety wear.
  5. Keep in mind that it may be more cost effective to spend a little more on strong and durable eyewear now than to have to replace a flimsy pair later. Each office differs in the warranties they offer and the length and terms of coverage. Ask your optician about what is and is not covered under their frame and lens coverage policy.
  6. If your child is put into bifocal lenses for reading issues or poor focusing issues (commonly used in pediatric vision therapy) they will generally require a deeper frame in order to have enough room for the bifocal, which is often difficult when dealing with smaller frames.
  7. Consider a blue light protecting anti-reflective coating. Children are especially prone to damage from blue wavelengths of light because their human lenses are so clear. Blue light is emitted from many of the devices we use such as cell phone screens, tablets, laptops, TVs, and the sun as well.

The great news is that the options in children’s eyewear in terms of style, quality and innovation is progressing rapidly. Rather than dreading the eyewear shopping experience, have a positive attitude. This will have a positive influence on your child’s relationship to eyewear and good vision that can last a lifetime.

Preventing Age-related Macular Degeneration

dad riding bike with daughter

February is AMD and Low Vision Awareness Month in the United States, and it’s White Cane Week in Canada. Age-related Macular Degeneration (AMD) is a leading cause of vision loss in adults aged 50 and older. Awareness about the disease, the risk factors and prevention are critical, even for younger generations because taking care of your eyes while you are young will help to reduce the risks later on in life.

Understanding AMD

AMD is a disease that damages the macula, which is the center of the retina responsible for sharp visual acuity in the central field of vision.  The breakdown of the macula eventually results in the loss of central vision and can occur in one eye or both eyes simultaneously. While AMD doesn’t result in complete blindness, the quality of vision is severely compromised leading to what we refer to as “low vision”.

The loss of central vision can interfere with the performance of everyday tasks such as driving, reading, writing, cooking, or even recognizing faces of friends and family.  The good news is, there are many low vision aides on the market now that can assist in helping you to perform these tasks. 

There are two types of AMD, wet and dry.

Dry AMD is the most common form of the disease. It is characterized by blurred central vision or blind spots, as the macula begins to deteriorate. Dry AMD is less severe than the wet form, but can progress to wet AMD rapidly.

Wet AMD is when abnormal blood vessels begin to grow under the retina and leak fluid and blood into the macula, causing distortions in vision. Wet AMD can cause permanent scarring if not treated quickly, so any sudden blur in vision should be assessed immediately, especially if one is aware that they have AMD.

Are You at Risk?

The biggest risk factor for AMD is age. Individuals over 60 are most likely to develop the disease however it can occur earlier.  Additional risk factors include:

  • Smoking: According to research smoking can double the risk of AMD.
  • Genetics and Family History: If AMD runs in your family you are at a higher risk. Scientists have also identified a number of particular genes that are associated with the disease.
  • Race: Caucasians are more likely to have AMD than those from Hispanic or African-American descent.
  • Lifestyle: Obesity, high cholesterol or blood pressure, poor nutrition and inactivity all contribute to the likelihood of getting AMD. 

Prevention of AMD:

If you have risk factors, here is what you can do to prevent or slow the progression of AMD:

  • Regular eye exams; once a year especially if you are 50 or over.
  • Stop smoking.
  • Know your family history and inform your eye doctor.
  • Proper nutrition and regular exercise: Research indicates that a healthy diet rich in “Eyefoods” with key nutrients for the eyes such as orange peppers, kale and spinach as well as regular exercise may reduce your risks or slow the progression of AMD.
  • Maintain healthy cholesterol levels and blood pressure. 
  • Dietary supplements: Studies by the National Eye Institute called AREDs and ARED2 indicated that a high dosage of supplements of zinc, vitamin C, vitamin E and lutein may slow the progression of advanced dry AMD (it is not recommended for those without AMD or early AMD).  Speak to a doctor before taking these supplements because there may be associated risks involved. 
  • Wear 99% -100% UV-blocking sunglasses.

The first step to eye health is awareness. Help us to spread the word about this debilitating disease and the importance of choosing a healthy lifestyle.

Resolve to Prevent Glaucoma in 2016

Glaucoma 20Eye 20Diagram

This year, make healthy eyes and vision your resolution. Find out if you or a loved one is at risk for glaucoma, and take steps for prevention.

Glaucoma is a leading cause of preventable vision loss and blindness in adults in the United States and Canada and the second leading cause of blindness in the World. Projections show that the number of people with the disease will increase by 58% by 2030. These facts however could change with proper awareness.

When detected in the early stages, glaucoma can often be controlled, preventing severe vision loss and blindness. However, symptoms of noticeable vision loss often only occur once the disease has progressed. This is why glaucoma is called “the sneak thief of sight”. Unfortunately, once vision is lost from the disease, it usually can’t be restored.

Risk Factors

Prevention is possible only with early detection and treatment. Since symptoms are often absent regular eye exams which include a glaucoma screening are essential, particularly for individuals at risk for the disease. While anyone can get glaucoma, the following traits put you at a higher risk:

  • Age over 60
  • Hispanic or Latino descent, Asian descent
  • African Americans over the age of 40 (glaucoma is the leading cause of blindness in African Americans, 6-8 times more common than in Caucasians.)
  • Family history of glaucoma
  • Diabetics
  • People with severe nearsightedness
  • Certain medications (e.g. steroids)
  • Significant eye injury (even if it occurred in childhood)

What is Glaucoma?

Glaucoma is actually a group of eye diseases that cause damage to the optic nerve due to an increase in pressure inside the eye or intraocular pressure (IOP). Treatments include medication or surgery that can regulate IOP and slow down the progression of the disease to prevent further vision loss if detected early. The type of treatment depends on the type and the cause of the glaucoma.

What are the Symptoms?

Most times glaucoma does not have symptoms. There is no pain unless there is a certain type of glaucoma called angle closure glaucoma. In this case, the channel of outflow gets crowded then blocked, causing foggy, blurred vision, halos around lights, headache and even nausea. This is a medical emergency and should be assessed immediately as the intraocular pressure can become extremely high and cause permanent damage within hours.

Most forms of glaucoma have an “open angle”, which is not so urgent, but does need compliance with the treatment plan (which is sometimes difficult as some of the glaucoma drops have uncomfortable side effects). Once vision loss develops it typically begins with a loss of peripheral or side vision and then progresses inward.

What Can You Do To Prevent Glaucoma?

Because there are no symptoms, regular eye exams are vital to early detection. If you have any of the above risk factors or you are over 60, make a yearly comprehensive eye exam part of your routine. Make sure that your eye doctor knows your family history and any risk factors that are present.

A comprehensive eye exam can determine your risk of developing glaucoma; if you have been diagnosed with glaucoma and have concerns about your treatment, it is best to speak openly with your doctor. Remember, a simple eye doctor’s appointment on a regular basis could save your vision for a lifetime.

Why Do We Need Glasses?

The most well-known part of a comprehensive eye exam is the basic vision test. When you have a general vision test, one of the main conditions the eye care practitioner is checking for is a refractive error. A refractive error means there is an abnormality in the shape of the eye, changing the eye’s ability to focus light directly onto the retina.This causes blurred vision and can usually be corrected by wearing prescription eyeglasses, contact lenses and possibly, alternate treatments such as vision therapy, ortho-k, LASIK or refractive surgery such as LASIK.

 

The term, “refractive error” refers to a problem with the process of refraction that is responsible for sight. Normally, light rays that enter your eye are refracted or bent through the cornea and the lens, and ultimately converge or are focused onto a single point on the retina. From the retina, messages are sent through the optic nerve to the brain which then interprets these signals into the image that we are seeing.   

 

In order for this process to work effectively, the anatomy of the eye including the length of the eye and the curvature of the cornea and the lens must be just right to be able to focus the light onto the retina. When this is not the case, a refractive error will occur.

 

There are several different types of refractive errors, depending on which part of the eye is affected, and it is possible to have multiple refractive errors at the same time:  

 

Myopia or nearsightedness:

In myopia the length of the eyeball is too long which results in light coming to a focus in front of the retina, rather than on the retina. This allows the individual to see well when objects are close but not clearly when looking at objects at a distance.

 

Hyperopia or farsightedness:

Hyperopia is when the eyeball is shorter than normal and can result in near objects being blurry. However, people experience hyperopia differently. Sometimes distant objects are clear while other times people may experience overall blurred vision near and far or no problems at all. In children particularly, the lens may accommodate for the error allowing for clear vision but may cause fatigue and sometimes crossed eyes or strabismus. Hyperopia causes eyestrain or fatigue especially when looking at near objects for a period of time. Often people with 20/20 vision may still need glasses at their desk to relax their eyes and improve concentration.

 

Astigmatism:

Astigmatism is usually the result of an irregularly shaped cornea (although it can sometimes also be due to a misshapen lens). The cornea, which is normally round, is more football-shaped in an eye with astigmatism, resulting in multiple focus points either in front of the retina or behind it (or both). People with astigmatism usually have blurred or distorted vision to some degree at all distances, near and far.

 

Presbyopia:

Presbyopia is an age-related condition which usually begins to appear sometime after 40.  As the eye begins to age, the lens stiffens and can no longer focus clearly on objects that are close.  

 

It’s important to note that presbyopia is often confused with hyperopia, as both cause problems focusing at near distances.  However, high hyperopia can also cause blur at far distances as well, especially in dim lighting, and depth perception problems can result in motor vehicle accidents.  In these instances people with hyperopia could use glasses at any distance.

If you are having trouble seeing, it is important to have an eye exam to determine the cause of the problem and to effectively correct your vision. Even if your vision is fine, you should schedule a routine eye exam on a regular basis to ensure that your eyes are healthy and that any potential problems are caught early.
