ABSTRACT:
A facial air cleaner adapted to remove airborne particles in the vicinity of a person's face prior to insertion of contact lenses to eliminate the airborne particles from being deposited on the contact lenses during insertion. The cleaner is an enclosed unit which has an air inlet driven by an electric fan and conduit connected to the inlet adapted to provide a pattern of high and low velocity air flow through outlets arranged to surround the face and gently flood the hand holding the lens with cleaned air while a lens is being inserted.
