What Is Cataracts?


Nearly everyone will develop cataracts at some point. Cataract is the term used to describe a clouding of the natural lens of the eye. This clouding of the lens is part of the normal aging process. Cataracts most often start to cause a noticeable difference in vision after 60 years of age. However, the formation of a cataract can be accelerated by many other factors besides age. These factors include trauma to the eye, infection, previous eye surgery and certain medications. Rarely, an infant is born with cataracts.


Are Cataracts Only Developed In Older People?


Most cataracts develop slowly over time and affect people over age 50. About half of the U.S. population has a cataract by age 65, and nearly everyone over age 75 has at least a mild cataract in one or both eyes.
