Common eye disorders

Vision loss can be caused by different problems in the eye:

Presbyopia makes it hard for the lens to focus.
Cataracts make the lens cloudy.
Glaucoma damages the optic nerve.
Macular degeneration damages the macula, the part of the eye that lets you see fine detail.
Diabetic retinopathy damages the blood vessels in the retina, the part of the eye that receives visual images and sends these images to the brain.
