London, Oct 9 : Researchers have now found a solution to the problem of losing the ability to blink after damage to the nerve that controls the process - a pair of glasses that sends a command to force a blink.

Blinking is essential for lubricating and cleaning the eye, the absence of which may result in permanent damage to the eye.

The glasses designed communicate with sensors attached to the eyelids' muscles.

The sensors report whether the muscles controlling the eyelid have contracted or not. If they haven't for a certain time, the glasses send a command to force a blink by stimulating the muscles electrically.

The team of researchers from the University of Pittsburgh says that the device can prevent eye damage by ensuring that the build up of dirt and bacteria is prevented by regular blinking. (ANI)
