ABSTRACT:
A contact lens insertion tool and a method of implementing the same wherein the tool comprises an elongated handle section having a top surface, a bottom surface, and two side surfaces; an intermediate section angularly displaced from the handle section at an acute angle; and a lens supporting section angularly displaced from the intermediate section at a second acute angle that is greater than the first acute angle, and further including a substantially circular cross sectional land area for engaging a contact lens. The novel contact lens insertion tool is first grasped by a user who will then manipulate the tool to adhere the contact lens to the land area by means of the adhesion between the lens and the land area. Next, the user will bring the contact lens edge first to the bottom central area of the sclera of the eye into which insertion is desired, and will secure contact between the lens edge and the eye at an angle ranging from approximately 20.degree. to not greater than 90.degree.. Finally, the user will rotate the tool upward until a point where the adhesion between the contact lens and the eye exceeds the adhesion between the contact lens and the land area of the contact lens insertion tool, thus disposing the contact lens in the user's eye.
