UV-Visible Transmittance of Silicone-Hydrogel Contact Lenses measured with a fiber optic spectrometer
Protein deposition is one of the most frequent contaminants occurring on hydrophilic contact lenses and may modify the lens optical properties. The silicone-hydrogel contact lenses usually adsorb a lower amount of proteins than the conventional hydrogel ones. However it is important to study the influence of protein deposits on some silicone-hydrogel contact lenses properties, such as UV-Visibl...
متن کاملP 153 Prevention of the eye against the damaging effect of UV rays by soft contact lenses with UV absorbers
HIRSCH M. PRENANT G. and POULIQUEN Y. INSERM lJ.86, H&e1 Dieu. Pari.v (France) Puroose. The objective was to determine the supramolecular organization of the cornea1 stroma extracellular matrix (ECM) and the changes which occured during the acquisition of transparency. Methods. Mature corneas and chicken embryo corneas were used. Samples were frozen against a metal block cooled at -18O”C, trans...
متن کاملInhibition of lens photodamage by UV-absorbing contact lenses.
PURPOSE To determine whether class 1 UV-blocking contact lenses protect against UVB radiation-induced damage in a human lens epithelial cell line (HLE B-3) and postmortem human lenses using a proteomics approach. METHODS HLE B-3 cells were exposed to 6.4 mW/cm(2) UVB radiation at 302 nm for 2 minutes (768 mJ/cm(2)) with or without covering by senofilcon A class 1 UV-blocking contact lenses or...
متن کاملPrevention of UV-induced damage to the anterior segment using class I UV-absorbing hydrogel contact lenses.
PURPOSE To determine whether class I ultraviolet (UV) light-blocking contact lenses prevent UV-induced pathologic changes in a rabbit model. METHODS Twelve rabbits were assigned to 1 of 3 treatment groups (n = 4), as follows: senofilcon A (class I UV blocking) contact lenses; lotrafilcon A contact lenses (no reported UV blocking); no contact lens. The contralateral eye was patched without a c...
متن کاملDiurnal changes in epidermal UV transmittance of plants in naturally high UV environments.
Studies were conducted on three herbaceous plant species growing in naturally high solar UV environments in the subalpine of Mauna Kea, Hawaii, USA, to determine if diurnal changes in epidermal UV transmittance (T(UV)) occur in these species, and to test whether manipulation of the solar radiation regime could alter these diurnal patterns. Additional field studies were conducted at Logan, Utah,...
