Computer Vision Syndrome: Causes and Prevention

The unrelenting push for digitalization gives us ubiquitous electronic screens as a constant in almost every facet of our lives. Many jobs available today require sitting for hours in front of a digital screen. Workers complain of tired eyes and other symptoms that affect their quality of life. Doctors call it computer vision syndrome—the new kid on the block of common eye conditions.

What Is Computer Vision Syndrome?

Eyestrain has been around for as long as people have been doing close-up work like reading or writing. However, computer vision syndrome is a relatively new form of eyestrain with much more impactful symptoms.

It is more popularly known as digital eyestrain; fortunately, it can be remedied through different noninvasive strategies. But if your symptoms persist even after using the techniques, they likely stem from an underlying condition. 

What Causes Computer Vision Syndrome?

The main cause of computer vision syndrome is the prolonged use of digital screens in poor environments and setups. The Vision Council reports that over 85% of all people in the United States use one or more digital devices for more than two hours a day. Moreover, at least 76% of children spend two hours on a digital screen daily.

Some of the situations that cause computer vision syndrome are:
 

• Working in a poorly lit room—either too brightly lit or dimly lit—for prolonged periods

• Concentrating on a close-up task that is visually demanding for a long time

• Experiencing some types of poor vision conditions or dry eye

• Stress or feeling fatigued

What Are the Direct Causes of Computer Vision Syndrome?

Computer vision syndrome occurs due to factors directly connecting to the above mentioned situations. Here are the factors that lead to the condition:
 

• Poor posture when using digital devices

• Prolonged periods exposed to blue light from digital devices and computers

• Using poorly lit screens when working

• Low blink rate when using computers or digital devices

• Holding a digital screen too close to your face

How to Prevent Computer Vision Syndrome

Take Breaks

First, you must take breaks every few hours. Taking breaks will allow your brain and eyes to relax and reduce the impact of blue light. Taking short 20-second intervals while you work every 20 minutes would be best. At this time, you can look away at something 20 feet away to relieve the stress from close-up work. 

Position of the Screen

The screen's position in terms of height and distance works towards the development of computer vision syndrome. Ideally, your screen should be below or at the same level as your eyes and arms-length away. 

Lighting

Lighting plays a crucial role in developing this condition; a few adjustments can help mitigate it. The room you work in should not be too bright and should not cause glare on your computer screen. You can change the position of your desk to alter how light falls off your screen.
