Stay away from smoke: Smoking can up a personís risk for multiple chronic health conditions, including cataracts and age-related macular degeneration, according to the Office of the Surgeon General. Just one more reason why you should quit smoking or, better yet, never even start.
Keep blood sugar and pressure in check: Fluctuating blood sugar and blood pressure levels can harm the miniscule blood vessels in the retina, potentially leading to vision problems, and even blindness. Diabetics and those with high blood pressure should take care to keep their levels in check to preserve the health of their eyes.
Give over-exerted eyes a break: Americans spend much of their time in front of a computer screen, which puts a lot of pressure on our peepers. If you while away the days staring at a digital screen, the National Institutes of Health (NIH) suggests adhering to the 20-20-20 rule to cut down on the potentially damaging effects eye strain. Every 20 minutes, spend 20 seconds staring at a spot 20 feet in front of you (at the opposite wall, or out the window).
One final tip for anyone over 50 years of age: get an annual comprehensive eye exam.
Many age-related eye diseases have few or no symptoms in the beginning. You may not be able to feel something is wrong until itís too late. Going in each year to have your eyes fully-dilated and checked out is the best way to catch a problem before it steals your sight.
