Maybe You’ve Never Heard of Computer Vision Syndrome
Computer Vision Syndrome, or CVS, is the term for eye and vision issues resulting from extended exposure to computer screens. The severity of the syndrome is linked to the amount of time that one spends in front of their screen or monitor.
Computer Vision Syndrome is not limited to just computers, either. Extended use of any digital screen, including the ever-popular tablets and smartphones, can lead to CVS. And the condition is becoming more widespread, in line with the all-encompassing Digital Age and the continued implementation of computers into our daily lives.
In fact, reports from the Vision Council have concluded that about 70 percent of the adult population experiences symptoms associated with Computer Vision Syndrome. Further, there is growing concern for the American youth population, as the early exposure and prevalence of digital screens among children and teens in both recreational and educational settings has become commonplace.
What Are the Symptoms of Computer Vision Syndrome?
Symptoms associated with CVS can range from mild to more serious, and typically involve pain or issues with vision. Common symptoms include dry eyes and blurry vision, along with headaches, strained eyes, and pain in the shoulders and region of the cervical spine.
Those with existing vision problems are especially at risk for developing Computer Vision Syndrome. Conditions like astigmatism and age-related presbyopia are examples of vision deficiencies that can increase the chances of developing CVS.
How Can Digital Screens Strain the Eyes and Affect Vision?
In addition to the presupposing factor of existing vision problems, causes of Computer Vision Syndrome can include posture, digital screen glare, improper lighting, and sitting at an unsuitable distance from the computer screen. Neglecting existing vision problems can also attribute to the development of CVS.
The act of staring at a computer screen places a lot of demand on the eyes. Words are much easier to read on the printed page, as the letters are usually more defined, in addition to the contrasting background. According to the American Optometric Association, those who spend more than two uninterrupted hours a day in front of a digital screen are at the highest risk for developing Computer Vision Syndrome.
Treatment and Prevention for Computer Vision Syndrome
There are a number of ways to treat and prevent the development of Computer Vision Syndrome. Those who spend long hours in front of digital screens tend to blink less than normal — one of the main underlying causes for dry eyes. With that in mind, taking frequent moments to blink while in front of a computer screen should help prevent the eyes from becoming dry and irritated. Modest use of eye drops may also be beneficial.
Taking breaks from the digital screen can also help alleviate symptoms and prevent CVS. For headaches and blurred vision, incorporate the 20-20-20 rule, which recommends focusing on an object at least 20 feet away for 20 seconds every 20 minutes.
Since lighting and viewing distance are contributing factors to Computer Vision Syndrome, addressing these issues can help eliminate many associated symptoms. People commonly stare too closely, so remember to push back the digital screen. Dimming the screen and keeping surrounding light low to reduce glare can reduce eye strain.
Lastly, correcting existing vision problems is paramount to maintaining the health of your eyes and preventing Computer Vision Syndrome. Be sure to get regular eye exams and update vision prescriptions, as needed. In some cases, computer-specific eyewear may be recommended. Ask your eye care specialist whether you’re a candidate for computer glasses.
