What is computer vision syndrome?
CVS is a serious type of repetitive strain injury that affects your vision along with other aspects of your physical health. It is also known as digital eye strain and happens when you look at the screen for a long time with a bad posture. Using digital screens for extended periods of time without enough rest for the eyes leads to strain, discomfort, pain, and vision problems, among other symptoms.
The distance between your eyes and computer may contribute to an increased risk of computer vision syndrome. While you can safely hold a newspaper, magazine, or notebook closer to your face but the computer screen is different.
Your chair or desk may be at the wrong height for you, which contributes to trouble in seeing. It can also result in other types of physical strain like neck or shoulder tension.
Symptoms of computer vision syndrome:
- Eyestrain
- Headaches
- Blurred vision
- Dryness in eyes
- Eye fatigue
- Neck and shoulder pain related to head and eye tension
The causes of these symptoms are:
- Poor lighting in the room.
- Glare from the digital screen.
- Improper viewing distance, either too close or too far away.
- Poor seated posture.
- Uncorrected vision problems.
- Blinking less than normal.
How is it detected?
Visit your optometrist when you experience the above-mentioned symptoms.
Ways to prevent it?
- One simple method to prevent is the 20-20-20 rule. Work on a digital screen for 20 minutes, then take a break for 20 seconds and then look at something 20 feet away.
- Adjust the level of your screen in accordance to your eyes.
- Sit at an arm’s length distance from your computer screen
- Take short breaks to blink
- Use eye drops if your eyes feel itchy and dry.
