New-Generation Silicone Hydrogel Contact Lenses Can Alleviate Some Common Problems of Soft Contact Lens Wear

New contact lens technology may help alleviate Computer Vision Syndrom ...

"While nearly 88 percent of all computer users will develop Computer Vision Syndrome at some time in their lives according to the National Institute of Occupational Safety and Health, a new nationwide study of Americans' attitudes and experiences with vision care reveals that contact lens wearers are more likely than non-wearers to experience at least one of the symptoms often associated with the disorder. Now, new research demonstrates that the use of new-generation silicone- hydrogel lenses (senofilcon-A) can alleviate some of these problems.

Nearly half (45 percent) of computer users report they at least sometimes experience dry or tired eyes during or after using a computer, but contact lens wearers are significantly more likely than non-wearers (57 percent vs. 43 percent) to describe these symptoms. Furthermore, one-third of contact lens wearers (36 percent) polled say they experience contact lens discomfort while working at a computer according to findings from Americans' Attitudes and Perceptions About Vision Care, a nationwide survey of more than 3,700 adults conducted by Harris Interactive® on behalf of The Vision Care Institute(TM) of Johnson & Johnson Vision Care, Inc.

"The unique characteristics and high visual demands of computer work make many individuals, particularly contact lens wearers, susceptible to the development of eye and vision-related problems," explains Dr. Jeffrey Anshel, a practicing optometrist and author of Visual Ergonomics in the Workplace. "Research shows that while using a computer, we blink about three times less than normally. These long non-blinking phases can cause the surface of most contact lenses to dry out, which can lead to extreme discomfort and a loss of visual clarity."    (Continued via Yahoo!
