Vision problems

Vision problems can include short-sightedness, far-sightedness, astigmatism, presbyopia, floaters and flashes, macular degeneration, and retinitis pigmentosa.

The eye is like a big screen television. The eye muscles, cornea and lens are constantly adjusting in order to focus the light on the retina, the light-sensitive membrane at the back of the eyeball.

With prescription glasses or contact lenses or surgery, most people with blurry vision are able to see clearly again.
