Abstract
Today's corrected curve lenses are being challenged by newer aspheric lens designs. These lenses use flattened aspheric front surfaces to provide lenses that look better and more comfortable. Sola Optical's ASL trademark aspheric lenses in Spectralite trademark and Polycarbonate, have taken this a step further by combining the benefits of high index/low weight materials with the optical performance of Sola's aspheric lens design. This combination provides thinner, lighter, and better looking lenses while maintaining excellent visual performance. Sola engineers have identified the factors critical to understanding and managing the blurring effects of off-center aberrations in lenses. ASL lenses are up to 25% thinner, 30% lighter, and 30% flatter than standard plastic lenses without sacrificing optical performance. In addition, they reduce magnification so images appear more natural in size, as do the wearers' eyes.
