To get your eyes checked you have to take an appointment go visit the optometrist and then go through a series of test. All the equipment involved like an Aberrometer in the test costs a lot. Poor countries and civilizations cannot afford it and are therefore deprived from quality vision. But now the function of the Aberrometer has been shrinked to just a small lens device and a smart phone screen.
A team at MIT media labs consisting of Ankit Mohan, Manuel M. Oliveira Neto, Vitor Pamplona and Ramesh Raskar have come up with an amazing prototype device and a software which lets to detect the power of refractive errors in your eye anyplace anytime.

The whole system consists of three things, a plastic device consisting of a lenses, a mobile phone and a software installed on the cellphone. The plastic device is clipped to the cellphone screen. Then the patient looks through the lens to see a pair of parallel lines, now the patient has to press the arrow keys until the parallel green and red lines seem to overlap. This is repeated 8 times with different angles for each eye, the software comes up with prescription data. The devices has no moving parts and hence no maintenance. The software is based on a technology called Bokodes which was developed last year which helps to store a large amount of information on a tiny square code.
