Try our cataract simulator

How to use the cataract simulator

Enter an address, location or postcode in the box below and click Go. You’ll be taken to your location and shown a vision simulation of what it would look like if you had cataracts. Use the left and right buttons on your keyboard, or the buttons on the side of the map, to rotate the screen and see more of the cataract simulator.

What does the world look like when you have cataracts?

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 we created this cataract simulator to give you an idea of what it’s like.

Could you imagine living with this vision every day? Having to cross busy roads, read at school or work, spend time with your friends? If you’d like to help a person suffering with cataracts, please consider giving a donation, below.
