Eye: Cataracts


Normally, light passes through the lens of the eye so that the image can be projected clearly on the retina. This image is then interpreted as a neural signal. If the lens is unclear, which is a condition called a cataract, the image projected on the retina will be cloudy or blurred.

Cataracts are common and occur naturally with aging.

If a cataract is interfering with vision significantly, it can be removed in a surgical procedure.
