Answers to Common Eye Health Questions

Premier Health providers answer frequently asked questions about eye health.

What is a cataract?

A cataract is a clouding of the eye’s lens, according to the National Institutes of Health(NIH).

A normal lens is clear, which lets light through to the retina in the back of the eye, according to the U.S. Department of Health and Human Services Office on Women’s Health (HHS).

The eye’s lens is made up of water and protein, according to the NIH. The protein is arranged specifically to let light through and keep the lens clear.

But this protein can start to clump together as people age, forming the cataract and making the lens cloudy, according to the NIH.

Though a cataract can form in one or both eyes, it can’t spread from one eye to another, according to the NIH.

For more information about cataracts, talk with your physician.
