Bausch and Lomb PureVision Contact Lens Helps Correct Spherical Aberration

Filed under category: Wearables

The Bausch and Lomb PureVision soft contact lens, now available in the United States, is designed to correct spherical aberration, a condition that researchers estimate effects nearly 70-percent of the population, in addition to correcting for nearsightedness and farsightedness. Spherical aberration, a so-called higher order aberration of the eye, may cause halos to appear around light sources in low-light conditions including dawn and dusk.

Bausch and Lomb PureVision lenses use AerGel technology to balance oxygen and water, an important factor in helping to maintain all-day comfort. In addition to comfort, the PureVision lens's silicone hydrogel material is a healthy option regarding corneal edema for contact lens wearers because it allows more oxygen to get to the surface of the eye than traditional hydrogel lens materials.
