摘要:
Squeezed, the flexible cup of the device forms two convex lips which grip a soft contact lens in place on a human eye, deforms the lens, breaking its fluid suction-bond to the eye, allowing easy and gentle removal of the lens from the eye, without fingers touching the eye. The body of the device has a dished end with an elevated rim, an annular lumen and a depressed central segment, which end safely holds soft contact lenses by the variable suction of a flexible bulb, controllable by sliding the other end of the body into the lumen of the bulb. The lens is released by squeezing the bulb.
