You've probably experienced computer eye strain if you spend more than two hours a day focused on a computer, whether you are working, studying, surfing the web, watching TV shows or interacting on social media.
More than 70 percent of the 143 million Americans who work on a computer every day experience computer eye strain, according to the American Optometric Association.
Hours at a time on the computer can lead to other symptoms which are known collectively as computer vision syndrome or CVS.
If you experience any of these symptoms after using the computer, you may have CVS:
• Headache or brow-ache
• Blurred or out-of-focus vision
• Double vision
• Burning or tired eyes
• Twitches in the eye
• Neck and shoulder pain
• Increased sensitivity to light
Computer screens create images by combining tiny dots of light into groupings that we see as words or other images.
Computer vision syndrome occurs because words and images on a computer screen have a lower definition and contrast compared to printed words on a page. This makes our eyes work harder to focus on the computer, resulting in eye strain.
Try these tips to reduce computer eye strain:
• Get your eyes checked
The first step is to make sure your eyes are healthy and your vision is good. Some people find that having a special pair of glasses just for use when on the computer helps relieve computer eye strain. Your eye doctor will need to know the distance between your eyes and your computer screen to determine the right prescription for you.
• Minimize glare
Many computer screens and monitors have a special finish to reduce glare on the screen. But light glare around your computer screen can also contribute to eye strain.
Try to balance lighting with the brightness of your computer screen. This may mean having a dimmer light in the room, closing drapes, and turning off or reducing the number of fluorescent light tubes in your work area.
• Screen placement
Having the right computer screen at the right distance is important to ease eye strain.
