Smartphone to Diagnose Cataracts

Using your Smartphone could help you detect early Cataracts according to researchers at Massachusetts Institute of Technology (MIT). The Camera Culture group of the Media Lab at MIT developed a device called Catra which clips on to a Smartphone and then scans the light as it enters and exits the eye which can help to detect the presence of a Cataract. The Catra device can detect Cataracts at a earlier stage than existing tests because it can pick up changes in parts of the crystalline lens that have not yet been clouded. By presenting a series of green dots to the patient on the phone scanning software it allows for the mapping of the lens that tells the size,shape, location and density of the Cataract.
