Computer Vision

Computer vision syndrome (CVS) is a group of symptoms caused by extended screen use. It has become increasingly common as people spend more time on computers, tablets, and smartphones, affecting all ages.

CVS occurs when long periods of screen use force your eyes to work harder, especially if your prescription is not properly corrected for computer use. Additional strain from glare, flicker, and screen brightness can also contribute to discomfort.

Symptoms may include headaches, blurred vision, dry or itchy eyes, eyestrain, and neck or shoulder pain. Not everyone experiences all of these symptoms, but even a few can make work or school more difficult.

Symptoms may become more noticeable with age, especially after 40, when presbyopia can affect near focusing ability.

If you regularly notice these issues, an eye exam with your optometrist is a good first step toward relief. Special computer glasses may significantly help reduce CVS symptoms

What Happens if I have CVS?

There is currently no proof that CVS causes long-term vision impairment or blindness. Continuing to use a computer or any other type of screen can continue to be an annoyance or reduce your ability to see properly. Some of the warning signs of CVS are:

• Blurred vision

• Double vision

• Red or dry eyes

• Headaches

• Neck pain

• Back pain

• Eye Irritation

• ​​​​​​​Itching
  

If you don’t properly treat CVS when these symptoms occur, you may begin to notice that you suffer from a decrease in overall quality of life or job performance.

Treatment Options

Computer vision syndrome (CVS) can often be improved with simple changes to your screen habits and workspace.

Reducing glare can help ease eye strain by adjusting your screen angle controlling lighting, using blinds or adding a screen filter. Proper desk setup is also important. Your monitor should sit slightly below eye level and about 20–28 inches from your eyes to avoid neck and eye strain.

Adjusting your screen settings, such as brightness, contrast, and font size, can make viewing more comfortable. Taking regular breaks using the 20/20/20 rule (every 20 minutes, look 20 feet away for 20 seconds) also helps reduce fatigue.

Ensuring your prescription is up to date can significantly reduce eye strain. Anti-glare coatings or blue light blocking lenses can provide additional relief.
