Try our cataract simulator

Cataracts are caused by a build-up of protein that clouds the eye’s lens, which can lead to blurred vision and eventual blindness. Cataracts cause blindness for more than 12 million people worldwide. Everyone experiences this sight loss differently, but to give you an idea of what it’s like, we’ve created the cataract simulator below.

How to use the cataract simulator
