On the front of its Business Day section, the New York Times reports that “2013 has been the Year of the High-Tech Glasses,” all designed to improve vision. The piece goes on to showcase new Adlens Variable Focus lenses which can use knobs to “precisely adjust the liquid pressure on a curved membrane inside the lens, affecting its power (from –4.5 to +3.5 diopters).” OxAmp Color-Assisting glasses are designed for medical professionals to give “a ‘clearer view of veins and vasculature, bruising, cyanosis, pallor, rashes, erythema, and other variations in blood O2 level, and concentration,’ especially in bright light.” The glasses also help correct for red-green colorblindness in some individuals.
