Paper Abstract

The aim of this study is to benchmark the optical properties (transmittance, absorption and dispersion) of two different types of contact lenses (daily replacement hydrogel - Hioxifilcon A and monthly replacement silicone-hydrogel - Asmofilcon A) in the visible spectra using the IAD method. Lower transmittance, lower absorption and higher dispersion were found for daily replacement contact lenses - Hioxifilcon A - than for monthly replacement contact lenses - Asmofilcon A. As diopter powers increase for both type of lenses, transmittance and absorption decrease and dispersion increases, which may have implications on the visual performance of these contact lenses.
