The evaluation of spectral transmittance of optical eye-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.
