A comprehensive eye exam is essential for detecting any eye problems in their early stages, regardless of your age or physical health. Even if you have 20/20 vision, an eye exam can provide an indication of your overall health. The eyes are the only place in the body where arteries and veins can be seen without requiring surgery. An eye exam can detect signs of stroke, diabetes, cardiovascular disease, brain tumours, multiple sclerosis, and other diseases.
They can also tell if someone has age-related macular degeneration, diabetic retinopathy, glaucoma or cataracts, as well as low vision, which is a condition associated with these age-related eye diseases.
