CATRA is an innovation of MIT's Media Lab that uses a cellphone and a inexpensive cosmetic eyepiece to discover cataracts. Not usually is it cheaper and simpler to use than existing solutions, it obviously provides sufficient improved results.
Cataracts result in blindness by fogging the lens of the eye, pinch light before it reaches the retina. Normally, they are diagnosed using a "backscatter" device that shines light in to the eye and measures how sufficient of it is reflected by the cataract. This requires a expert user, a like appurtenance and still doesn't discover the complaint early, nor discuss it the user what the studious obviously sees.
CATRA uses a smartphone with a law app, and a inexpensive eyepiece. The studious binds it up to their eye and the app fires light constantly at any segment of the eye. The studious uses "the phone's arrow keys" to arrange the liughtness of these beams until they match. The app logs the differences in severity compulsory to attain the retina and creates a chart of the eye. Therefore is can discover the complaint early, and moreover reflects the real experience of the patient.
But many important, it requires no special hardware solely for that elementary eyepiece.
The product is about to bear margin contrast for a future launch. The marketplace for this is evidently the building world, that is moreover the place where cellphone use is receiving off. It might be time to dont think about about programs like One Laptop Per Child and instead combine on the using smart-phones instead.
