Abstract
An apparatus for protecting the eyes of a dental or medical practitioner from exposure to ultraviolet radiation during the illumination of a surgical site or other area of interest includes first and second carrier lenses positioned within a suitable frame. The first carrier lens comprises first and second regions wherein the first region is adapted to transmit substantially all visible light incident thereon and wherein the second region is adapted to absorb or reflect all ultraviolet light incident thereon and at least some light incident thereon having a wavelength above 400 nm. At least a portion of the second carrier lens is also adapted to absorb or reflect both ultraviolet light and at a portion of light incident thereon having a wavelength above 400 nm. This configuration protects the practitioner from exposure from the ultraviolet portion of the electromagnetic spectrum but permits the practitioner to view an area of interest via a non-absorbing region of at least one lens when a clear view of the area is desired. Each carrier lens is also adapted to receive a magnifying lens to provide the practitioner with a magnified image of an area under inspection without necessitating removal of the protective device.
