May is Healthy Vision Month

May is Healthy Vision Month

What does that mean for you? It means that now is the time to schedule a comprehensive eye  exam. 

While these are one of the exams we may often let fall by the wayside, they are extremely important to maintain our eye health. Comprehensive eye exams serve several purposes. During these exams, pupils, the circular black area in the center of the eye where light enters, are widened with eye drops or viewed without dilation through a special camera. This allows your Eye Doctor to check for vision problems and eye diseases, verify what stage of diseases your eyes may be in, and helps determine if you need glasses, contacts or other treatments. 

Comprehensive eye exams are crucial for all ages, here’s why: 

Pediatric exams test for visual acuity, lazy eye, color vision, ocular health, and more. These are extremely important to test for the school years ahead. 

For older children and teenagers, myopia (nearsightedness) is one of the biggest concerns that comprehensive eye exams detect. Myopia affects the eye’s ability to see distant images clearly. It is important to identify and treat early with glasses or contacts as children and teens begin to learn in larger spaces, play sports, and drive. 

Adult exams are recommended at least every two years, or as recommended by your eye care specialist. Exams for adults are necessary to catch eye conditions that can cause vision loss and even lead to blindness. Some of these conditions are cataracts, diabetic retinopathy, glaucoma, and age-related macular degeneration. 

There are several other conditions that comprehensive eye exams can expose that may not be found without a visit to your optometrist. 

Outside of eye exams, here are 5 ways you can help protect your vision: 

  1. Healthy eating. You know this! Healthy eating helps every part of your body. For your eyes, make sure to add dark, leafy greens and seafood that is high in omega-3 fatty acids to your plate. A great excuse to treat yourself to sushi! We’re adding a spicy sake maki roll to our cart… for delivery.
  2. Protective eyewear. Whether you’re chopping wood for the bonfire pit, mowing the lawn, painting your bedroom walls, or riding your motorcycle around town, protective eyewear is key. Blue-light protection glasses should also be considered to protect your eyes from all the time spent in front of computer screens.
  3. Sunglasses. Much like protective eyewear, sunglasses help protect your eyes from ultraviolet radiation delivered by sun. Not all sunglasses provide the same level of protection. Let us help you pick the best pair!
  4. Clean hands. Wash your hands before putting your contacts in and before taking your contacts out, simply to avoid infection.
  5. Stop smoking. Smoking is known to cause several diseases, but it can also lead to vision loss. It can increase the risk of age-related macular degeneration, cataracts, and more. Mark your calendar for your comprehensive eye exam and mark it as the day to stop smoking.

In our modern world, people spend hours on end staring at computer screens, smartphones, tablets, e-readers, and books that require their eyes to maintain close focus.

For most people (all except those who are nearsighted and aren’t wearing their glasses), their eyes’ natural focus point is far in the distance. In order to move that focus point from far to near there is an eye muscle that needs to contract to allow the lens of the eye to change its shape and bring up-close objects into focus. This process is called accommodation.

When we accommodate to view close objects, that eye muscle has to maintain a level of contraction to keep focused on the near object. And that muscle eventually gets tired if we continuously stare at the near object. When it does, it may start to relax a bit and that can cause vision to intermittently blur because the lens shape changes back to its distance focal point and the near object becomes less clear.

Continuing to push the eyes to focus on near objects once the focus starts to blur will began to produce a tired or strained feeling in addition to the blur. This happens very frequently to people who spend long hours reading or looking at their device screens.

An additional problem that occurs when we stare at objects is that our eyes’ natural blink rate declines. The average person blinks about 10 times per minute (it varies significantly by individual) but when we are staring at something our blink rate drops by about 60% (4 times per minute on average). This causes the cornea (the front surface of the eye) to dry out faster. The cornea needs to stay moist in order to see clearly, otherwise little dry spots start appearing in the tear film and the view gets foggy. Think about your view through a dirty car windshield and how much that view improves when you turn the washers on.

So what should you do if your job, hobby or passion requires you to stare at a close object all day?

Follow the 20-20-20 rule. Every 20 minutes, take 20 seconds and look 20 feet into the distance. This lets the eye muscle relax for 20 seconds, and that is generally enough for it to have enough energy to go back to staring up close for another 20 minutes with much less blurring and fatigue. It also will help if you blink slowly several times while you are doing this to help re-moisten the eye surface.

Don’t feel like you can give up those 20 seconds every 20 minutes? Well if you don’t, there is evidence that your overall productivity will decline as you start suffering from fatigue and blurring. So take the short break and the rest of your day will go much smoother.
