The spectral transmittance characteristics of each of thirty-two solid tint hydrogel contact lenses available in the United Kingdom were investigated using a dual beam spectrophotometer. Good agreement was found with the small number of spectral functions that had previously been published. Lenses with similar colour appearances were seen to differ markedly in terms of their transmittance factors. The importance of visual performance and radiation protection is discussed in the light of the spectral transmittances of the lenses.

D003116 Color The visually perceived property of objects created by absorption or reflection of specific wavelengths of light. Colors
D003261 Contact Lenses Lenses designed to be worn on the front surface of the eyeball. (UMDNS, 1999) Lenses, Contact,Contact Lens,Lens, Contact
D013053 Spectrophotometry The art or process of comparing photometrically the relative intensities of the light in different parts of the spectrum.
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.
