Spectral transmission characteristics of tinted lenses. 1981

B Borgwardt, and G A Fishman, and D Vander-Meulen

A total of 90 prescription and commercially available tinted lenses were evaluated for spectra transmission characteristics. An inappropriately large number of these lenses transmitted unnecessarily high amounts of light in the near ultraviolet, visible, and near infrared portions of the spectrum. No criteria regarding lens composition, color, or cost could reliably predict the effectiveness of individual lenses.

UI	MeSH Term	Description	Entries
D007259	Infrared Rays	That portion of the electromagnetic spectrum usually sensed as heat. Infrared wavelengths are longer than those of visible light, extending into the microwave frequencies. They are used therapeutically as heat, and also to warm food in restaurants.	Heat Waves,Heat Wave,Infrared Ray,Ray, Infrared,Rays, Infrared,Wave, Heat,Waves, Heat
D003116	Color	The visually perceived property of objects created by absorption or reflection of specific wavelengths of light.	Colors
D005139	Eyeglasses	A pair of ophthalmic lenses in a frame or mounting which is supported by the nose and ears. The purpose is to aid or improve vision. It does not include goggles or nonprescription sun glasses for which EYE PROTECTIVE DEVICES is available.

D013057	Spectrum Analysis	The measurement of the amplitude of the components of a complex waveform throughout the frequency range of the waveform. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)	Spectroscopy,Analysis, Spectrum,Spectrometry
D014466	Ultraviolet Rays	That portion of the electromagnetic spectrum immediately below the visible range and extending into the x-ray frequencies. The longer wavelengths (near-UV or biotic or vital rays) are necessary for the endogenous synthesis of vitamin D and are also called antirachitic rays; the shorter, ionizing wavelengths (far-UV or abiotic or extravital rays) are viricidal, bactericidal, mutagenic, and carcinogenic and are used as disinfectants.
