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.

Who can forget the news of the capturing of Osama Bin Laden by our US Special forces? An interesting fact was that the Navy Seal unit that made the capture attributes much of their military success to NVGs (night vision goggles). The capture of Bin Laden, along with numerous captures of Al-Qaeda members in Desert Storm, came from night vision capabilities that were provided by this ocular technology.

The top of the line NVG has a sophisticated four tube version of an earlier model, and costs upwards of $60,000 to $65,000 per pair. They have superb capabilities to see into enemy lines for our military.

So what exactly are NVGs and what is the technology behind them? What other visual expectations do our military troops use to give us the edge in a battle?

Expertly made night vision goggles can spot a target close to 200 years away. NVG use infrared and thermal detection technology to capture the image in the darkest of circumstances. The electronic information that comes from the NVG has no color. but in order for our eyes to see it, a green picture is emitted from the screen.

What exactly do you have to be able to see to enter the military as a pilot of a plane or helicopter? To understand this, it helps to understand the difference between corrected and uncorrected vision. 20/20 vision is the ability to achieve "Normal" vision.

In other words, the patient sees the same line of letters at 20 feet that a normal person sees at 20 feet. A patient with 20/15 vision can see objects at 20 feet that a person with 20/20 vision can only see at 15 feet. Corrected vision means you can achieve 20/20 vision with glasses or contacts. Uncorrected vision is your vision without glasses or contacts.

Here are the military requirements listed by branches of the military:

Army: 20/50 uncorrected (correctable to 20/20)

Air Force: 20/70 uncorrected (correctable to 20/20)

Navy and Marine Corps: 20/40 uncorrected (correctable to 20/20)

Pilots must pass a color vision test and have normal depth perception or 3-D vision.In regards to Laser Vision Correction (LASIK), since 2007 it has no longer become a deterrent to entering the military as a pilot, as the restriction has been lifted for potential pilots.

With the knowledge of ophthalmic technology, and the requirements to achieve optical clarity for the military, its no wonder they have the cutting edge in most wars and battles. So whether you use NVG for hunting, military use, or just recreational activity, its helpful to know and understand the “why” behind the know how, and be able to appreciate the capabilities of night vision goggles.

Exciting headline news comes understanding the technology behind the capture of Bin Laden!
