6144508 - Self-viewing device for eyes

An apparatus for detailed and sharp self-viewing of the eye including the cornea or surface of the eye comprises a tube-like housing with a diffused light source at one end. The light source projects light through a pin-hole in the center of a baffle in the tube housing towards a convex lens near the other end of the tube housing. When a user holds the tube housing with the convex lens close to his eye, a sharp and detailed image of the eye is projected into the tube and may be viewed by the user. The device is particularly useful for self visual inspection of the condition of the eye cornea, for inspecting contact lenses for air bubbles or debris lying between the lens and the eye, and for inspecting the installation and condition of piggy back lenses.
