Understanding Cataracts

Cataracts are a common eye problem that affects millions in the U.S. They cause a cloudy lens that makes it hard to see. Our eyes have a lens that focuses light, but as we get older, proteins in this lens can clump together, clouding it³.

Many people are affected by this condition. About 24.4 million Americans over 40 have cataracts, and this number is expected to grow³.

What Are Cataracts?

A cataract happens when the lens in your eye gets cloudy. This blocks light from reaching the retina. It usually happens slowly, changing your vision over time⁴. The proteins in the lens start to break down, making your vision hazy or blurry.

Types of Cataracts

Nuclear Sclerotic Cataracts: Develop in the center of the lens
Cortical Cataracts: Form around the lens edges
Posterior Subcapsular Cataracts: Occur at the back of the lens

Statistics on Cataracts in the U.S.

Cataracts have a big impact. By 80, over half of Americans have them or have had surgery³. Every year, 1.5 million people in the U.S. get cataract surgery, with a success rate of 95%⁴.

The number of people with cataracts is expected to rise by 50% by 2030. This is mainly because more people are getting older³. Getting regular eye exams and wearing UV-blocking sunglasses can help prevent or slow cataracts³.

Symptoms of Cataracts

Cataracts are a big problem for vision that gets worse over time. Knowing the early signs helps people catch vision changes early. This way, they can get help fast⁵.
