The Effects Of Today's Technology On One's Vision

SAN DIEGO, Dec. 10, 2013 -- Approximately 40 percent of Americans spend three or more hours per day looking at a computer screen or hand-held device, and those numbers are expected to increase during the holidays with all the iPads, DS's, and learning tablets that will be given as presents this holiday season.[1] While the compulsion for technological devices has grown, so have the associated vision-related disorders such as computer vision syndrome (CVS), which affects approximately 90 percent of individuals who spend three or more hours per day looking at a computer screen. Dr. Sandy T. Feldman -- a nationally-recognized ophthalmologist and corneal expert at Clearview Eye & Laser Center in San Diego -- warns patients that these problems could turn into more serious vision issues if left untreated or unaddressed.

"If we as a society are going to continue to rely on technology and technological devices in both our personal and professional lives, we must also take precautions to help prevent or reduce the strain that technology is having on our eyes," said Dr. Feldman. "Studies show that between 50 to 90 percent of people who work on a computer experience some sort of issue with their vision. These numbers will only continue to grow -- especially during the holidays when people have more free time -- if we don't take the necessary steps to protect our eyes from all the overstimulation."

To rule out any potential vision issues, Dr. Feldman offers the following tips to help reduce the risk of overstimulation on the eyes and prevent other major vision problems from developing:

  • Reduce the glare -- Changing the lighting in a room or using a glare filter over a computer screen or cell phone can help to protect the eyes. One can also try moving the monitor or phone around and/or closing the blinds or shades until the glare disappears.
  • Rest the eyes -- In order to give eyes a break, it is best to look far away from the screen every 20 minutes and focus on another object for at least 20 seconds. To keep eyes moist, individuals should try and blink often or use eye drops to lubricate the eyes if necessary.
  • Make adjustments at your desk -- Experts suggest that a computer monitor should be positioned slightly below eye level, with approximately 20 to 28 inches separating the monitor and one's face.
  • Adjust computer settings -- In addition to adjusting elements in one's immediate surroundings, the settings on the computer can be adjusted as well. Individuals should adjust the font size, contrast, and brightness until their eyes become well adjusted.
  • Use an app adjust the computer background light to approximate natural light - This might help reduce overstimulation and being kept awake by exposure to bright white light.
