The development of Peek (Portable Eye Examination Kit) is allowing smartphones to become diagnosis tools for your eyes.

The project is spearheaded by the London School of Hygiene and Tropical Medicine in partnership with other various medical organizations to bring better medical care to the third world. The project is being tested on 5,000 people in Kenya who might not otherwise have access to eye doctors.

The app uses the smartphone's camera to scan the eye for cataracts and activates the camera flash to scan the back of the eye for disease. It employs a shrinking letter on the screen to conduct eye exams and examiners can keep track of patients by storing their records on the phone.

At the moment, the product is still in it's trial stages, but it's already looking promising. The results of the on going study and efficacy of Peek's eye test have been encouraging.
