Air exposure between blinks affects deposits on contact lenses
Date:11/5/2012

Philadelphia, Pa. (November 5, 2012) - Modern contact lens materials are prone to drying when exposed to air, which contributes to the buildup of deposits on contact lenses, according to a study "The Impact of Intermittent Air Exposure on Lipid Deposition", appearing in the November issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

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, Ont., Canada. The findings may help in developing new materials that are less prone to drying and lipid depositionthus increasing the chances of successful contact lens wear.

Air Exposure Leads to Increased Lipid Deposits on Contact Lenses

The researchers built a new experimental setup, called the "model blink cell," to examine factors affecting the buildup of lipid (fatty) deposits on contact lenses. The model blink cell was designed to cycle contact lens materials in and out of an artificial tear solution containing trace amounts of cholesterol or other lipids naturally present in tear fluid.

To mimic the effects of routine lens wear, six different contact lens materials were subjected to simulated blinks and eyelid motion for varying pe
