Computer Vision Syndrome: A digital Age Epidemic 

By Dr. Jessica Xu

Many people experience higher visual stress when doing intensive near-work at digital screens, a health problem called Computer Vision Syndrome (CVS). Symptoms of CVS include eyestrain, headaches, ocular discomfort, eye pain, dry eye, double vision, blurred vision and photophobia.

CVS has been known among computer professionals for several decades. It not only affects their health, but also their job performance. European Union and Australia have passed laws in occupational health to protect workers using electronic/digital screens regularly.

As digital devices become prevalent in our daily lives, CVS now affects the general population. About 90% of computer users experience CVS at various severities. Some users suffer only minor eyestrain, some have only dry eyes, while others experience much more severe symptoms and vision deterioration. Eyestrain, headache, nausea and eye pain usually disappear in several hours to several days after stopping using computers. However, dry eye, photophobia and blurred vision may take several days to months to recover after stopping using computers.

In many cases blurred distance vision do not recover and the person becomes myopic, commonly known as nearsighted. The problem is particularly common among children and young adults. With prevalence of digital devices, school myopia has surged among children and young adults in recent decades.

Dry eye can stay for a prolonged time as well. It was rare for children to have dry eyes before the digital device boom. Now pediatric optometrists notice increasing incidences of dry eye among children.

As schools adopt more and more educational technology, CVS becomes a very common health problem among school children. The trend is so difficult to reverse that it is predicted that a large population will have poor vision in near future.

The good news is that using educational technology in PUSD is optional. Parents can choose the more eye-friendly paper option in schools for their children, at least to prevent their children’s vision from sharp deterioration at a young age. For children with severe CVS, parents can apply for 504 plan for their children until their eyes become strong enough for intensive near-distance digital screen work. And, it is always helpful to encourage kids to minimize their screen time.

Our children’s eyes are precious. Let’s take good care of them.
