Smartphone Add-On Can Quickly Detect Cataracts

Composed of inexpensive components, this new self-diagnosis system is perfect for the developing world.

Today’s smartphones can now help detect eye ailments, thanks to the efforts of researchers from the MIT. Using handy off-the-shelf components, Media Lab Camera Culture led by Ramesh Raskar developed the CATRA system, a device that scans the lens of the human eye for signs of cataract, the leading cause of human blindness. The CATRA utilizes a forward scattering technique, which allows the user to respond to what they visually experience specifically. Based on what the user sees, the CATRA can make an intelligent diagnosis of the severity of the eye condition.
