Future Uses Of The Mobile Phone...
|13 February 2012|
Researchers at the MIT University in the US have developed a software application and a plastic lens type device to fit to the phone so to be able to undertake low-cost eye exams. As in the photo, the plastic lens piece is clipped onto the lens of the phone, the patient looks into the lens, and presses the phone's arrow keys until sets of parallel green and red lines just overlap. This is repeated eight times, with the lines at different angles, for each eye.
The whole process only takes two minutes, at which point the software loaded onto the phone then provides the prescription data.
