Abstract

Polarized lenses are recommended because exposure to intense sunlight damages cellular function and photoreceptor structures in the eyes. Polarized lenses filter all wavelengths of UV radiation and most of the reflected glare due to strong reflections depending on the angle of incidence of sunlight and environmental factors. The wavelength of mineral glass in the horizontal and vertical direction (~550nm) is 16.64% for (CF1) and 13.21% for (CF2). There is a sudden drop of 27.87 at 729nm in CF2 and a sudden increase to 58.80 at 730nm in CF1. Absorbance values at 730nm are 0.21 with a decrease in AF1 and 0.54 with an increase in AF2. CF2 is polarized. To determine how the structure of the lens material affects light transmittance and absorbance, the light transmittances of smoked mineral and organic lenses of the same color are 16.64 for the mineral lens and 22.47 for the organic lens at (~550nm) wavelength. Maximum transmittance is 81.25 for mineral lens and 85.73 for organic lens. For night vision, at (~507nm) wavelength, it is 19.35 for mineral lens and 25.00 for organic lens. At (~550nm) wavelength, absorbance values are 0.78 for mineral lens and 0.62 for organic smoked lens. In the study, the effect of color factor on the light transmittance and absorption of organic smoked, brown and green polarized lenses was investigated. Light transmittance at 550 nm wavelength is 22.47 in smoked, 13.48 in brown and 14.32 in green. Absorbance at 550 nm wavelength is 0.62 in smoked, 0.94 in brown and 0.82 in green lens. Since dark lenses do not allow high light transmission, smoked color should be chosen for good vision in the visible light region. Brown color should be preferred if dark glasses should be used in situations where bright light is intense. In the 507nm wavelength of color polarized lenses, smoked is 25.00, brown is 11.45 and green is 16.94. Smoked should be chosen for night vision.
