London: Blind people can soon have their sight restored, thanks to a device that uses the tongue to help them see.

The device involves a camera mounted on a pair of glasses being connected to a sensor on the patient`s tongue, which then sends signals from the camera to the brain, bypassing the user`s damaged eyesight, a newspaper reported.

A camera attached to the glasses captures a moving image. The BrainPort device transfers the image via a cable to a lollipop attachment on the tongue.

Electrodes tingle on the tongue to reflect the image with darker areas creating stronger pulses.
