What is a cataract?
Cataract: A cataract is a clouding of the lens of the eye. Like a dirty camera lens, a cataract interferes with your eye’s ability to bring images into sharp focus, transmitting a clouded or distorted picture to the brain.
Cataracts are a breakdown of natural proteins in the eye. These proteins clump together, growing larger until they affect vision.
A senile cataract is a type of eye disorder that is associated with age and occurs in older people. It is characterized by an initial opacity in the lens, followed by swelling of the lens. As the cataract gets worse, it shrinks and and becomes cloudy, impairing vision.
Another type of cataract is the Morgagnian cataract. Untreated, Morgagnian cataracts can cause phacomorphic glaucoma.
Symptoms of Cataracts
Common symptoms are nighttime glare, high sensitivity to bright light, blurriness and muted perception of colors.
