What is a Cataract?
Cataract is the term used to describe a clouding of the natural lens of the eye. A clouded lens can be compared to a window that is frosted or "fogged" with steam. When the lens becomes cloudy, the light reaching the retina is blurred and distorted, and your vision is affected. This clouded lens is called a cataract, and it must be removed before vision can be restored. Cataracts are not cancerous. They can be treated with a surgical procedure that has become a fairly common procedure in the United States.
Types of Cataracts
The two most common types of cataracts are: the cortical cataract and a posterior subcapsular cataract. Depending on the type of cataract, a patient will experience different vision problems, but the most common cataract symptoms include:
» Blurring vision
» Sensitivity to light or glare
» Double vision in one eye
» Poor night vision
» Needing brighter light to read
» Experiencing fading or yellowing of colors.
If the cloudiness is not near the center of the lens, you may not be aware that you have a cataract.
