If you use a computer frequently or for several hours daily, you may have experienced computer vision syndrome. It is a condition caused by prolonged digital screen use and is characterized by eyestrain, headaches, and dry eyes. 

Fortunately, experiencing CVS does not mean you have to give up your digital devices. Making some lifestyle changes can help prevent the problem. 

Computer Vision Syndrome

Computer vision syndrome, or digital eyestrain, is a condition that affects people of all ages. It can be mild or severe depending on the individual’s eye health and other factors. Prolonged use of digital devices, such as computers, tablets, smartphones, and e-readers, can lead to the condition.

Looking at the screens causes the eyes to work hard to focus as the words are not as sharp as those on printed material. There is also the issue of the light from the devices. Digital screens tend to produce glare, making focusing even more difficult.

Symptoms of Computer Vision Syndrome

CVS can lead to eye and vision problems. It can also cause discomfort in other parts of the body. Signs that you may have CVS include eyestrain or fatigue, headaches, blurry or double vision, and dry or tearing eyes. 

Other symptoms are itchy or red eyes, shoulder pain, neck pain, and back pain. You should visit your eye doctor if you experience the symptoms or notice sudden changes in your eyesight.  
 

Using a digital device for two or more hours continuously can produce the symptoms. 

Risk Factors for Computer Vision Syndrome

How you use your devices can increase your risk of developing CVS. Risk factors include:

Using a computer screen daily.

• Reflection or glare from a digital screen.
• Using digital screens in poor lighting.
• Uncorrected vision problems.
• Incorrect lens prescription.
• Poor posture when using digital devices. 
• Poor viewing distance. 
• If you have an underlying eye condition or existing eyesight issues, you are more likely to experience CVS. 

How to Prevent Computer Vision Syndrome

Changing how you use your digital devices can help ease computer eyestrain. Simple ways to ease the discomfort include:

• Adjust your computer to prevent straining and to make the text more visible.
• Blinking frequently when using your digital devices to prevent eye dryness.
• Using lubricating eye drops. 
• Using the right eyeglasses and keeping your prescription updated.
• Reducing or eliminating screen glare through proper lighting. 
• Improving your posture when using your digital device.  
• Taking regular breaks when using your devices. 

When to Visit Your Doctor

Eyestrain and other symptoms are usually temporary and go away when you stop using the device. But in some cases, the symptoms worsen, affecting the vision. If you still experience symptoms after making changes in how you use digital devices, it may be time to visit a doctor. 
 

Contact the doctor if you experience eye flashes, sudden vision changes, and unexplained eye redness or pain. If your eye dryness fails to improve with eye drops, visit an eye doctor. You can find out if you have dry eye syndrome. 

If you have computer vision syndrome, your doctor may recommend eyeglasses for computer use. Prescription eye drops and vision therapy can also help.
