Wear a hat or visor whenever you are outside, even on overcast days. Ultraviolet light passes through cloud cover and is just as dangerous as direct sunlight. To be on the safe side, try to find glasses that guard against all ultraviolet rays. A certain percentage of sunglasses are mislabeled, so always buy sunglasses from a reputable dealer. Your optician can check your glasses to measure the UV protection.
Most glasses allow some direct sunlight to enter from the top and sides of the frame.
There are sunglasses designed specifically for macular degeneration that include side panels and a ridge at the top of the glasses so that all light is filtered. The most helpful colors for blocking out blue light are red, orange, yellow and amber. Because glare is often a problem for people with AMD, choose this protection carefully. You can also have your regular glasses treated with ultraviolet protection - a clear coating that will not interfere with your sight. A healthy lifestyle that includes regular cardiovascular exercise also contributes to both cardiac and eye health.
