Although aging puts people at greater risk for serious eye disease and other eye problems, loss of sight need not go hand in hand with growing older. Practical, preventive measures can help protect against devastating impairment. An estimated 40% to 50% of all blindness can be avoided or treated, mainly through regular visits to a vision specialist.

Regular eye exams are the cornerstone of visual health as people age. Individuals who have a family history of eye disease or other risk factors should have more frequent exams. Don't wait until your vision deteriorates to have an eye exam. One eye can often compensate for the other while an eye condition progresses. Frequently, only an exam can detect eye disease in its earliest stages.

You can take other steps on your own. First, if you smoke, stop. Smoking increases the risk of several eye disorders, including age-related macular degeneration. Next, take a look at your diet. Maintaining a nutritious diet, with lots of fruits and vegetables and minimal saturated fats and hydrogenated oils, promotes sound health and may boost your resistance to eye disease. Wearing sunglasses and hats is important for people of any age. Taking the time to learn about the aging eye and recognizing risks and symptoms can alert you to the warning signs of vision problems.

Although eyestrain, spending many hours in front of a television or computer screen, or working in poor light does not cause harmful medical conditions, it can tire the eyes and, ultimately, their owner. The eyes are priceless and deserve to be treated with care and respect — and that is as true for the adult of 80 as it is for the teenager of 18.

computer screens affect your eyes due to the blue lighting built into their screens. Although it may not look like it, all computer screens (or any screens for that matter) contain something called blue light. Blue light damages you optic nerve which is situated in the back of your eye. The optic nerve acts as a mirror reflecting what the iris takes in onto your brain. Without your optic nerve your eye would still be able to take in the surroundings but it couldn't transmit those images to the brain which is the most important part of being able to actually see. The blue light damages the optic nerve by disrupting is mirror reflex this means that the optic nerve cant transmit those signals it picks up into your brain as fast as it would have originally. This is the main reason why computer screens damage your eyes and why you should reframe from using those screens at times when you can.
