Glaucoma is an eye disease caused by increased pressure within the eye. It is one of the most common causes of blindness and affects 250,000 Canadians. Although it often occurs in older people, it can develop at any age.
People with glaucoma probably lose their sight because increased pressure in the eye and other factors (such as poor blood flow) affect the optic nerve at the back of the eye. The eye slowly loses nerve function, and loss of side (peripheral) vision. This occurs painlessly, even unnoticeably.

A cataract is a clouding of the lens of the eye. The lens is located near the front of the eye. It focuses light on the retina, at the back of the eye, to form the images we see.
A cataract may affect just a small part of the lens, or it may cloud the entire lens. If your sight isn't badly impaired, the lens doesn't have to be removed. But if the central part of the lens is cloudy, you may not be able to see unless the lens is taken out.
