#1869: IrisIron

A research supervisior of mine once explained that getting iron fragments from munitions inside the eye had blinded many servicemen.

Today’s invention is a way to use magnmetic material to help improve vision.

Imagine three (or more) contact lenses joined to form a strip of varying optical power and placed on the iris as shown. These would have tiny ferromagnetic particles moulded into the edge.

A set of small, strong electromagnets embedded in the (optically neutral) glasses frames could be switched on and off in sequence to translate the lenses across the lubricated eye surface and thus offer a much more flexible visual augmentation than any normal lenses or glasses.

Ideally, the change in lenses could be driven by detection of a long blink for ‘move right’ and two such blinks for ‘move left’.
