Link between Lipid Deposits on CLs and Blinks

Modern contact lens materials are prone to drying when exposed to air, which contributes to the buildup of deposits on contact lenses, according to the study called "The Impact of Intermittent Air Exposure on Lipid Deposition." The results of the study appear in the November issue of Optometry and Vision Science, the official journal of the American Academy of Optometry. With significant differences between materials, the buildup of lipid deposits on contact lenses is affected by "intermittent air exposure" between blinks, according to Holly Loretz, PhD, and colleagues of the Centre for Contact Lens Research at University of Waterloo, ON. The findings may help in developing new materials that are less prone to drying and lipid deposition—thus increasing the chances of successful contact lens wear. Read more.
