With so many of us spending long hours on digital devices for work, school, and entertainment, it's no surprise that more people are experiencing eye discomfort. This condition is known as Computer Vision Syndrome (CVS), and it can cause symptoms like eye strain and headaches much faster than you might think.

What Is Computer Vision Syndrome?

Computer Vision Syndrome, also known as digital eye strain, refers to a group of eye and vision-related problems that result from prolonged screen use. When you spend hours looking at digital screens, your eyes must work harder. The constant focusing and refocusing, reduced blinking, and exposure to blue light can overwork the eye muscles and lead to discomfort.
 

Common symptoms of CVS include:
 

• Eye strain or tired eyes

• Headaches

• Blurred or double vision

• Dry eyes

• Neck and shoulder pain

How Quickly Can Symptoms Start?

Symptoms can begin to appear within just a few hours of screen use, sometimes even sooner if you are using poor posture, working in bad lighting, or not taking breaks. Some people experience eye strain and headaches after just 2 to 3 hours of continuous screen time, while others may develop symptoms over the course of the day.
 

Factors that contribute to faster onset of symptoms include:
 

• Improper lighting or screen glare

• Poor posture or screen positioning

• Uncorrected vision problems

• Lack of regular screen breaks

What Can You Do to Prevent It?

Fortunately, there are steps you can take to reduce your risk of developing Computer Vision Syndrome:
 

• Follow the 20 20 20 Rule: Every 20 minutes, look at something 20 feet away for at least 20 seconds to give your eyes a break.

• Adjust Your Screen Setup: Keep your screen about 20 to 28 inches from your eyes and slightly below eye level. Ensure your screen brightness is similar to your surroundings to reduce glare.

• Blink More Often: People tend to blink less when using screens, which can lead to dry eyes. Make a conscious effort to blink more frequently or use lubricating eye drops if needed.

• Use Proper Lighting: Avoid overly bright lighting from windows or overhead lights. Position your screen to reduce glare.

• Consider Computer Glasses: If you wear prescription glasses, ask your optometrist about lenses designed specifically for computer use. These may help reduce strain and improve comfort.

When to See Your Eye Doctor

If you regularly experience eye strain, headaches, or blurry vision after screen use, it is time to schedule an eye exam. Your symptoms could be a result of Computer Vision Syndrome or an underlying vision issue that needs correction. An optometrist can evaluate your eyes and provide tailored solutions to help you feel more comfortable during screen time.
