dc.description.abstractIn the present study, the effect of light on mineral (Quartz) and organic lenses (Diethylene glycol bis (allyl carbonate)-CR39, polycarbonate, trivex) is briefly reported. It is essential to choose the right conditions for ophthalmic lenses, such as the lighting environment in order to maintain the eye health. In this article, to discuss the harmful effects of ultraviolet radiation (UVR) on the lenses and to analyze the results of the visible-light transmittance, the properties of mineral and organic eye-lenses are investigated considering the personal eye-protections, ophthalmic optics, the transmittance requirements standards of scientific researches and the literature studies, by use of coated and uncoated prescriptive ophthalmic plastic concave and convex lenses. A UV-vis spectrophotometer device is used to determine the spectral transmittance of lenses in different diopters, index numbers and coating characteristics. Additionally, the physical and optical characteristics of eye-lenses, as well as their chemical characteristics and molecular structures are studied in this article. Also, the vibrational frequencies of organic lenses are investigated applying FT-IR device measurements, and the optimized molecular structure of CR-39 monomer by density functional theory (DFT) quantum chemical method is explained using B3LYP method with STO-3G and 6-31G as basis set.
