Computer Vision Syndrome Tips

Computer Vision Syndrome causes vision problems such as eyestrain, headaches, blurred vision, and dry eyes. Learn about preventing computer vision syndrome.The more technology evolves, the more difficult it can be to resist interacting with screens throughout the day. Nielsen confirmed this in June 2016 stating that adults in the United States spend around 10 hours and 39 minutes in front of screens per day. This means that using smartphones, laptops, computers, televisions, tablets, and other personal devices consumes almost half of the typical American adult’s day. As this usage increases, so does our susceptibility to Computer Vision Syndrome (CVS)

Computer Vision Syndrome (CVS) is defined by the American Optometric Association as “a group of eye and vision-related problems that result from prolonged computer, tablet, e-reader, and cell phone use.” CVS typically results in only temporary vision problems such as eyestrain, headaches, blurred vision, and dry eyes, it is also possible for these symptoms to continue even after screen interaction has stopped. That’s why device users must be educated on their susceptibility to Computer Vision Syndrome and be aware of ways to prevent it.

While the obvious suggestion to prevent Computer Vision Syndrome is to eliminate or decrease our daily screen time, this is easier said than done since our lives require interacting with these devices. Instead, follow these three simple tips to help prevent vision problems:

  • Match the brightness of your screen to the lighting of the room you are in
  • Maintain proper posture when using devices by sitting up straight and having relaxed shoulders
  • Follow the 20-20-20 rule of every 20 minutes, take a 20-second break 20 feet from a screen

It is important to listen to our bodies as well as follow these guidelines to prevent vision problems that come with our constant interactions with screens. The more we pay attention, the less susceptible we might be to Computer Vision Syndrome.

5 Tips in Preventing Computer-Eye Strain

Computer Eye StrainYou’ve probably had a headache from sitting and staring at a computer screen too long. Especially with contacts lens, you know that dry blinking feeling that comes after a couple hours at a desktop. There’s actually a name for this – computer vision syndrome (CVS). Contact and glasses wearers generally report more issues than non-wearers. Either way, there are a few things you can do to avoid issues.

  • See your eye care specialist regularly: Out-of-date prescription can be to blame for computer eye strain. (Consult a LASIK specialist to determine if LASIK or another similar procedure could get you the vision you desire.)
  • Square up to your computer: The screen should be about an arm’s length away and positioned in front of you. Don’t turn to one side to see your screen – your monitor should be about 4 inches below your line of vision so your gaze is slightly down.
  • Use good posture: Sitting or standing requires some intention. Roll your shoulder back and down to reduce strain for your neck, shoulders and back.
  • Take a break: Staring and glaring isn’t nice in a social setting and it’s probably not good for your computer work either. A break every 15 mins for a quick stretch is recommended.
  • Blink: No matter what amount of time you’re spending looking at a screen remember to be good to your eyes and blink. On average, when we’re awake, people blink 25 a minute. Blinking keeps your eye clean by using natural tears. It’s an automatic reflex, but when you’re deep in thought it’s good to give an additional and intentional blink to give the eyes a rest.

Five tips don’t make up a comprehensive list, but a couple more things to consider are lighting and computer glare. Some people find that computer glasses help and cleaning the screen of your computer can freshen up your space from dust while giving your eyes a more clear sharper image for your eyes to focus.
