Abstract
Apparatus for inserting and removing contact lenses has an adjustable horizontal plate for receiving the user's forehead, and for orienting the user's eyes relative to lens holding members. The apparatus has two adjustable pivoted blocks, each having substantially vertical, separate lens-inserting and lens-removing devices which can be selectively rotated into operating position for insertion or removal. The forehead plate is aligned at an angle approximately 3.degree.-10.degree. below horizontal to facilitate insertion and removal.
