How Disabling is Blindness?

The first worldwide Glaucoma Day was held this year in March, with much publicity, free testing by ophthalmologists, and free information given out. Glaucoma causes blindness if left untreated long enough. Cataracts also cause blindness when left untreated, and the treatment is to remove the entire lens from the eye, replacing it with an artificial lens such as Crystalens, ReSTOR, or ReZoom.
