Learning about the causes of low vision, some of the common risk factors that lead to low vision, and scheduling regular screening of your eyes are the key to protecting your sight as you grow older. So why delay, the best time to protect your eyesight is now!
It is the loss of sight that cannot be corrected even with contact lenses, prescription eyeglasses, or surgeries. Low vision does not include total blindness because you have slight sight left. It can be offset or treated with visual aids like magnifying glasses.
Low vision is divided into two categories based on the vision in the best eye:
Legally blind: When your vision is perhaps not better than 20/200 and that too with conventional correction. Or you may be having a restricted field of vision below 20 degrees wide.
Partially sighted: Your vision lies between 20/40 and 20/200 with conventional prescription lenses.
Loss of central vision: You have a blind spot in the centre of your vision field.
Loss of peripheral (side) vision: You cannot see anything above or below eye level. However, your central vision is intact.
Night blindness: You cannot see in places that are not adequately lit, such as in theatres or at night.
Blurred vision: When this happens, objects near and far seem to be out of focus.
Hazy vision: The field of vision appears to be covered with a glare or film.
If you have been suffering from near-sightedness (myopia), astigmatism, or farsightedness (also known as hyperopia), then you must know that there are no particular remedies to improve eyesight and vision without corrective eyewear. However, there are a few things that you can follow to improve and maintain your eye health and enhance your vision. The common ones are as follows:
If your diet contains yellow and orange-colored foods, then you are eating right. Foods like carrots, egg yolks, oranges are good sources of lutein and zeaxanthin. These nutrients protect us from Age-related Macular Degeneration or AMD. AMD is among the most common causes of blindness in older individuals.
Consuming a significant amount of sugar is usually bad for the body, including the eyes. Several studies have linked foods with high sugar content to age-related macular degeneration (AMD) that causes blind spots in central vision.
Working in artificial light at a stretch and staring at screens for a prolonged period puts stress on our eyes. It is essential to take breaks from work. You can try walking away from your computers or looking away from mobile screens.
Smoking is bad for your lungs, heart, skin, teeth, and eyes as well. Smoking significantly increases your risk of susceptibility to developing cataracts and age-related macular degeneration. However, your eyes and other organs can recover from any tobacco-induced damage if you quit smoking.
Exercising eyes is like exercising your legs or arms. Your muscles get stronger, you get more stamina, and you are less likely to experience further vision impairment. Here are some exercises that can help improve vision.
Each time you shut the eyes, your Meibomian glands start producing moisture that cleanses eyes. Blinking helps eyes feel refreshed and makes them ready to focus again, thus reducing eye strain.
This exercise helps the eyes become more flexible and stronger. The steps to perform the figure 8 exercise are:
Look to your right and left a couple of times without moving the head. Next, look up and down a few times.
