Scientists from Stanford University have created a smartphone eye exam add-on device that can turn a regular smartphone into a sophisticated eye-examination tool. The device consists of a pair of adapters that are simply added on to a smartphone's existing camera. One camera takes pictures of the front surface of the eye, while the other renders light through the pupil to get pictures of the retina at the back of the eye.
This smartphone eye exam technology means that patients won't have to rely on ophthalmologist offices equipped with large machines for eye exams. This could be especially useful for physicians in rural areas, developing countries or places ravaged by natural disasters where large eye-exam equipment may not be feasible. It could also be a godsend for emergency room personnel who require instant information to make important medical decisions.
The device is designed to make it easy for anyone to take pictures of their eye and share it with their doctor. It is currently being tested in clinical trials at Stanford University.
