NETRA smartphone eye test

NETRA (near-eye tool for refractive assessment) is a system for prescribing eyeglasses developed at MIT that uses an inexpensive plastic lens attached to a smartphone. the project is part of MIT’s media lab and provides an alternative to large, expensive diagnostic machine typically used for prescribing eyeglasses. the effectiveness and low cost of NETRA make it a viable way of providing vision correction to people in the developing world. to use the device, the patient simply slides the attachment onto the phone and runs a custom application. the user sees a series of red and green lines through the lens, which they adjust using the phone’s controls until the overlap. after completing this task the application calculates the user’s eyesight. the developers hope to launch the product soon in africa and asia.
