The device called NETRA (Near Eye Tool for Refractive Assessment) can be clipped on to a mobile phone with a suitable hi-resolution LCD display.

It can then detect whether you need glasses. The test takes less than a minute.

Raskar explained that after attaching the device, those with perfect vision will see a single line, while shortsighted or longsighted people will see multiple or distorted lines.

It will also help people figure out the power of the glasses they need.

'Eyecare is a low priority area in India. Eyeglasses can help almost 300 million people,' Raskar said.
