Abstract

Tokai Optical Company in Okazki, Japan, has developed a new line of CR-39 medical lenses designed to manage certain ocular and visual disorders. Before these lenses can be incorporated into the medical market, it is necessary to verify the selective filtration characteristics claimed by Tokai Optical Company. Using a modified Varian OMS 200 UV/Visible Spectrophotometer, Tokai Optical 'CC Filter' lenses were analyzed and compared to the transmission properities published by the manufacturer. It was concluded that the spectral transmission results differ by no more than 3.5 percent transmittance with the majority being less than 1.0 percent difference. The historical use of spectrally selective lenses in the treatment, management and prevention of ocular and visual disorders is also discussed.
