According to the Prevent Blindness Vision Problems in the U.S. report, more than 22.3 million Americans have cataracts.
What is a Cataract?
A cataract is a clouding of the eye’s lens, which blocks or changes the passage of light into the eye. The lens of the eye is located behind the pupil and the colored iris, and is normally transparent. The lens helps to focus images onto the retina – which transmits the images to the brain.
Your vision may become blurry or dim because the cataract stops light from properly passing through to your retina.
How common are cataracts?
Cataracts are a leading cause of blindness among older adults in the United States. More than half of all Americans have cataracts by the time they are 80 years old. Cataracts can also sometimes be found in young people or even newborn babies.
