Local optometrists provide valuable insight into the effects of computer screens and your vision.
More than 75 percent of America's workforce is now using computers on a daily basis. The majority of these professionals are performing close-up computer work for most of their workday - a task the human eye was not designed for.
Although office personnel have performed close up work for centuries, the proliferation of computers and the replacement of paperwork with computer work have triggered a host of new vision problems related to the use of computers.
Dr. Craig D. Crouch, Optometrist at Vision Care Associates, said it's not uncommon for people to come in with concerns about working on a computer.
"The most common symptoms are eyestrain, headaches, blurred vision and dry eyes," Crouch said. "Our eyes have trouble keeping the letters clear, constantly refocusing and overworking our eye muscles."
The complex of eye and vision problems related to work experienced during computer use has been termed "computer vision syndrome."
Many individuals who work at a computer experience eye-related discomfort and visual problems. However, it is unlikely that the use of computers cause permanent changes or damage to the eyes or visual system. Vision problems experienced by those working at a computer are generally only temporary and will decline after stopping work at the end of the day.
"There are no long term effects of working at a computer," Crouch said. "Those who work at a computer are just more likely to have dry eye and eye strain."
The use of a computer is associated with a decreased frequency of blinking and an increased rate of tear evaporating, each of which contributes to dry eyes.
