What Is Computer Vision Syndrome?
As technology advances, electronic devices such as computers, smartphones and tablets have become part of everyday life. Increased screen time can cause a range of symptoms affecting vision and eye health. Together, these symptoms are known as Computer Vision Syndrome (CVS), also called digital eye strain.
When does it occur?
Viewing a computer or digital screen often makes the eyes work harder. This extra effort can cause irritation and fatigue.
A digital environment may also aggravate dry-eye symptoms, especially during long periods of computer work.
We normally blink about 15 times per minute. When working in front of a digital device, the blink rate may fall considerably. This can leave the eyes tired and contribute to Dry Eye Syndrome.
What are the symptoms?
Many people who use digital devices experience at least some symptoms. These can include eye pain and fatigue, headache, dryness, burning, irritation, itching, watering, a foreign-body sensation, blurred vision and, occasionally, double vision. Together, these symptoms are often described as digital eye strain or asthenopia.
How is it managed?
Many symptoms are temporary and improve after stopping screen work. Regular eye care and changes to the way digital devices are used can often provide relief.
Regular use of artificial tears may help relieve symptoms when used as directed.
Regular eye examinations support eye health and help identify or reduce factors that contribute to CVS.
Make your eye health a priority today to support clear, comfortable vision for the years ahead.
Frequently Asked Questions: Computer Vision
It is a group of symptoms associated with prolonged digital screen use, including fatigue, dryness, blurred vision, headache and neck discomfort.
Common symptoms include stinging, a foreign-body sensation, temporary blur, difficulty focusing and headache.
Every 20 minutes, look at something about 20 feet away for 20 seconds to relax focusing and encourage blinking.
Reduced blinking during screen use can increase dryness. Take breaks and have the lens fitting assessed if discomfort persists.
An examination is needed when symptoms are frequent, severe or accompanied by persistent blur, pain or double vision, so other causes can be excluded.
