Inhibition 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 کاملRisk of UV exposure with spectacle lenses
Anti-reflection (AR) coating is an excellent spectacle lens option for increasing luminous transmission of the lens, reducing glare, and enhancing the cosmetic appearance of the wearer [4]. It is recommended for virtually all types of eyewear, including clear lenses for general, everyday use as well as nighttime driving; photochromic lenses for patients who frequently move between indoors and o...
متن کاملEfficiency analysis of diffractive lenses.
Multilevel diffractive optical elements are necessary for achieving high-efficiency performance. Here the diffraction efficiency of a multilevel phase-only diffractive lens is analyzed. Approximate, as well as more accurate, approaches are presented. Both plane-wave and Gaussian illumination are discussed. It is shown that for many practical cases the diffraction efficiency can be determined by...
متن کاملUV radiation protection by handheld umbrellas.
T he handheld umbrella (HU) is a commonly employed method of sun protection by women in many countries in Asia (45% in China) and the Middle East. In Turkey, hats and umbrellas were found to be the most common photoprotection accessories. The HU was standard outdoor attire for women of the 18th and 19th centuries in the United States. In the next century, sunscreen, hats, and sun-protective clo...
متن کاملIntra-Ocular Lenses for Cataract Patients
1989 was the 40th anniversary of intra-ocular lens implantation. Harold Ridley performed the first implant for cataract surgery in November 1949 at St. Thomas' Hospital. The idea developed on the following lines: It was known that trauma from plastic imbedded in the eye was inert, a situation seen mainly in air pilots who had suffered injuries from shattered windscreens. But the seed was sown b...
