Abstract

A low energy hydrogen ion shower (LEHIS) was used for the surface modification of Alyll Diglycol Carbonate (CR-39) ophthalmic lens samples. To investigate the changes in the physical, chemical, and optical characteristics, scanning electron microscopy (SEM), atomic force microscopy (AFM), Fourier transform infrared spectroscopy (FTIR) with attenuated reflectance accessory (ATR), and transmittance measurements were performed on treated and untreated 6x6 mm² samples. After treatment, SEM showed a decrease in surface nanosized structures and a change in structure size homogeneity, which corresponds with surface morphology data obtained through AFM. FTIR-ATR results showed minimal change in chemical structure while transmittance measurements showed increased values.
