Which device is used to assist with a droopy eyelid by holding the eyelid up?

A ptosis crutch is specifically designed to help support a droopy eyelid, a condition known as ptosis. It functions by providing a physical means to hold the eyelid in a more elevated and functional position, improving both vision and aesthetics for individuals affected by this condition. The device is typically attached to eyeglasses and applies gentle pressure to lift the eyelid, assisting those with weakness in the levator muscle, which is responsible for elevating the eyelid.

The other devices mentioned serve different purposes. An eye patch is used primarily to cover the eye for protection or healing, rather than providing support to the eyelid. An eye dropper is utilized for administering liquid medications directly into the eye, and an ophthalmoscope is an instrument used for examining the interior of the eye. Neither of these devices addresses the specific issue of supporting a droopy eyelid.
