Abstract

UV/VIS spectroscopic characterization of glasses is a part of the standard procedure. The reasons to do it is to ensure UV eye protection and characterization of material transparency. However, we extend this research to IR domain because the quality of glasses depend not only on UV protection and their transparency but on complementarities and compatibility of eye vision with optical device, also. We characterized basic material of glasses by UV/VIS/NIR and novel method Opto-magnetic Imaging Spectroscopy (OMIS). Then we doped basic material with fullerenes, and characterized them using the same procedure. Results are presented and discussed.

Highlights

People, who have perfect vision, most often use sunglasses for protection, while people with refractive anomalies use corrective glasses [1]
The abbreviations means that Red minus Blue wavelength of White light and reflected polarized light are used in spectral convolution algorithm to calculate data for opto-magnetic spectroscopy of matter [17]
According to opto-magnetic imaging spectroscopy results shown on diagrams, we can conclude that there is a dramatic difference in the values of the positive and negative peaks on Wavelength difference-Intensity (n.a.u.)

Summary

Introduction

People, who have perfect vision, most often use sunglasses for protection, while people with refractive anomalies use corrective glasses [1]. To achieve the desired results in vision correction, it is important to know the characteristics of materials used, because they can significantly affect the quality of visible light reaching different parts of the eye. Solar radiation comprises a broad range of wavelength, all of the eye disorders mentioned above are related to UV and short-wavelength visible light [4]. Because of the filtration effect of ocular structures, different wavelengths within the UV and visible light ranges penetrate through different parts of the eye (cornea, lens, and retina) (Fig. 1) [4]. Excessive UVB exposure can cause conjunctivitis and permanent damage to the cornea. Wavelengths between 295 and 400 nm penetrate more deeply and can cause damage to the crystalline lens (ie, cataracts) [5].
