The Research of UV Transmittance of Tinted Plastic Lens

Abstract

The purpose of this research is to set up the dyeing process of the plastic lens and measure the UV transmittance of the tinted plastic lenses which include UV-absorbing and non-UV absorbing. In experiment, the spectrometer (USB 2000) is used to measure the UV transmittance in both cases. Furthermore, the characters of the UV transmittance in different deep and light colors of the UV-absorbing tinted plastic lenses are compared. The results of the experiment in the UV-absorbing tinted plastic lenses are: the effect of the UV-absorbing tinted plastic lens better than that of non-UV absorbing tinted plastic lens. Among the deep color series, in the effects of UV-absorbing tinted plastic lens are: the deep green color is better than the deep red and blue colors. However, among the light color series, in the effects of UV-absorbing tinted plastic lens are: the light red color is better than light green and blue colors. According to the results, the consumers can have more choices in the UV-absorbing tinted plastic lenses.
