ABSTRACT:
An illuminated lens case for containing a plurality of diagnostic or therapeutic lenses used in eye examination and treatment in a darkened room comprises a container having a bottom wall, at least one side wall, and a top wall enclosing an interior space. One wall may be pivotally mounted to the container and adapted to swing between open and closed positions. The lens case further comprises a pair of vertically spaced horizontal shelf-like members which together with a side wall form a channel for attaching the lens case to a table top. A partition may divide the interior space of the container into a lens chamber and a battery and circuitry chamber. The lens chamber may contain an electroluminescent lamp in strip form at the bottom, and a lens holder having the plurality of recesses for receiving lenses disposed above the lamp. The lens holder is preferably made of polyethylene foam, which is both shock absorbing and translucent so as to diffuse light from the light source. The lens case may further include a battery and inverter with circuitry for powering the lamp, and a push button switch arranged so that the lamp is only illuminated when the top wall cover is open. Alternatively, a phosphorescent material may be disposed on the interior of the case to provide illumination.
