This useful device can be used to stablise any hard contact lens, particularly large diameter lenses like mini-scleral designs when inserting.
It can be worn on the end of a finger like and upside down ring for ease of lens insertion, or if preferred, can be held conventionally. Due to its convenient centre hole, the lens can be visualised through a mirror.
It is 3D printed to order, so size can be changed. Standard diameter is 15mm. It can be made out of glow in the dark plastic!
