ABSTRACT:
Individually marked contact lenses for protection of one's eyes from harmful radiation are provided. Contact lenses are coated or treated to be absorptive or reflective to a preselected wavelength or wavelengths. The lenses contain one or more identification areas on each lens to demonstrate that the lenses are being worn and to indicate the proper applications with which the lenses should be used and/or the wavelengths for which the lens is protective. The identification area, which should be visible when worn to third parties and/or the person wearing the lenses, consists of markings such as colored bands or shaded areas in the region around the iris. Different colors or color patterns of the markings indicate which wavelengths the lens protects against. Other safety features may include fluorescent markers, added features and devices to facilitate placement and retention in the eye, pick-up or release.
