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.

The 2017 National Coffee Drinking Trends report showed that 62 percent of more than 3,000 people who participated in the online survey said they had drunk coffee the previous day, which is interpreted as daily consumption. This was up from 57 percent in 2016, said the report, which was released at the coffee association's conference in Austin, Texas.

Even though the U.S. population is drinking more coffee than ever, the nation still only ranks 22nd overall in per capita consumption. The people of Finland average 3 times as much coffee consumption as people in the U.S.

So what does all this caffeine intake do to our eyes?

The research is rather sparse and the results are mixed.

Here are some major eye topics that have been investigated:

Glaucoma

One study, published in the journal Investigative Ophthalmology and Visual Science, showed that coffee consumption of more than 3 cups per day compared to abstinence from coffee drinking led to an increased risk for a specific type of Glaucoma called Pseudoexfoliation Glaucoma.

Another analysis of several existing studies by Li,M et al demonstrated a tendency to have an increase in eye pressure with caffeine ingestion only for people who were already diagnosed with Glaucoma or Ocular Hypertension, but no effect on people without the disease. A separate study, published by Dove Press, done with the administration of eye drops containing caffeine to 5 volunteers with either Glaucoma or Ocular Hypertension showed that there was no change in the eye pressure with the drops administered 3 times a day over the course of a week.

Summing up the available studies in terms of Glaucoma, the evidence points to maybe a slight increase in Glaucoma risk for people who consume 3 or more cups of coffee a day.

Retinal Disease

A study done at Cornell University showed that an ingredient in coffee called chlorogenic acid (CLA), which is 8 times more concentrated in coffee than caffeine, is a strong antioxidant that may be helpful in warding off degenerative retinal disease like Age Related Macular Degeneration.

The study was done in mice and showed that their retinas did not show oxidative damage when treated with nitric oxide, which creates oxidative stress and free radicals, if they were pretreated with CLA.

Dry Eyes

A study published in the journal Ophthalmology looked at the effect caffeine intake had on the volume of tears on the surface of the eye. In the study, subjects were given capsules with either placebo or caffeine and then had their tear meniscus height measured. The results showed that there was increased tear meniscus height in the participants who were given the caffeine capsules compared to placebo. Increased tear production, which occurred with caffeine, may indicate that coffee consumption might have a beneficial effect on Dry Eye symptoms.

Eyelid Twitching

For years eye doctors have been taught that one of the primary triggers for a feeling of twitching in your eyelid has been too much caffeine ingestion (along with stress, lack of sleep and dry eyes). I have been unable to find anything substantial in the literature to support this teaching. Therefore, I’m going to have to leave this one as maybe, maybe not.

The End Result

Overall, the evidence for the pros and cons of coffee consumption and its effects on your eyes appear to be rather neutral. There are one or two issues that may increase your risk for glaucoma but it also may decrease your risk of macular degeneration or dry eyes.

Since there is no overwhelming positive or negative data, our recommendation is--and this holds for most things--enjoy your coffee in moderation.
