People who have had to have a glass eye fitted can be left with a somewhat lifeless expression on one side of their face.
Today’s invention is a pair of glasses which a person with a glass eye can wear to reduce this effect.
A small camera in the frame surrounding their healthy eye can detect its angle of gaze.
This is communicated to the other half of the frame which contains a set of electromagnets.
These magnets act in concert to move a metal iris under the surface of the (static) glass eye, so as to mimic the movements of the healthy one.
