ABSTRACT:
A shaft member is slidably mounted in a flotation chamber. Liquid is fed to the flotation chamber from a liquid storage chamber through a constricted tube when the storage chamber is squeezed, thereby slowly raising the liquid level in the flotation chamber. By virtue of the buoyancy provided by the liquid, the shaft is raised vertically within the flotation chamber as the storage chamber is squeezed and the flotation level in the flotation chamber raised. Means are provided on the end of the shaft for supporting a contact lens. An eye piece is mounted on the device around the end of the shaft, such that the user's eye can be placed on the eye piece and the contact lens raised into contact with the eyeball in its installed position. The eye piece used for inserting the lens is removable and can be replaced with an eye cup which can be filled with liquid for use in removing the lens by bathing it out.
