Most people have been warned not to sit too close to the television because it can hurt the eyes. The warning may need to be extended to computer screens as well.

E-mails, shipping forms and interoffice communication at iLinc Communications are all accessed through computers. The company's business is online.

Employees began to notice some problems -- dry or sore eyes, dull headaches, constant blinking and more.

The problem is called Computer Vision Syndrome, or CVS. As one iLinc employee explained, the image on a computer screen is made up of pixels, which are dots of light with unclear edges. Trying to focus on the screen for long periods of time can strain the eye.

"It's like your eyes are doing pushups," she said.

Dr. Jim Frank said even people with perfect vision may not be immune to CVS.

"Some people have great distance vision, they can see the road signs miles away, but when you go to look at your screen, your eyes have a hard time focusing," Frank said.

A group of local doctors created the Vision Care Direct Computer Wear program, a vision care program specifically aimed at computer users. It includes a comprehensive eye exam using a PRIO tester, a device that simulates a computer screen so doctors can see how the patient's eye reacts to the screen.

The program allows doctors to design glasses and contact lenses for use with computers.

Janice Schafer said she's happy she found the cause of her headaches and blurred vision. Her treatment cost $259, and her company paid half.
