Computer Vision Syndrome 

Causes of Computer Vision Syndrome

Several factors contribute to the development of CVS:​

• Extended Screen Time: Spending prolonged periods staring at digital screens without breaks can strain the eyes.

• Poor Lighting Conditions: Inadequate or excessive lighting can cause glare on screens, leading to eye discomfort.​

• Improper Viewing Distances: Sitting too close or too far from the screen can force the eyes to work harder, causing strain.​

• Uncorrected Vision Problems: Existing refractive errors, such as myopia or hyperopia, can exacerbate CVS symptoms if not properly corrected.

Symptoms of Computer Vision Syndrome

Individuals experiencing CVS may notice:​

• Eye Discomfort: General discomfort or pain in and around the eyes.​

• Dry Eyes: A sensation of dryness or grittiness in the eyes.​

• Blurred Vision: Difficulty focusing clearly on the screen or objects at varying distances.

• Headaches: Frequent headaches associated with prolonged screen use.

• Neck and Shoulder Pain: Discomfort resulting from poor posture during screen use.​

Preventing Computer Vision Syndrome

To reduce the risk of CVS, consider the following strategies:​

• Follow the 20-20-20 Rule: Every 20 minutes, take a 20-second break to look at something 20 feet away. ​

• Ensure Proper Lighting: Adjust ambient lighting to minimize glare and reflections on the screen.​

• Maintain Appropriate Screen Distance: Position your screen about an arm’s length away and slightly below eye level.​

• Use Ergonomic Furniture: Ensure your chair and desk support good posture to reduce neck and shoulder strain.​

• Blink Frequently: Regular blinking helps keep the eyes moist and reduces dryness.

• Regular Eye Examinations: Schedule routine eye check-ups to ensure your vision is correctly corrected and to receive personalized advice on reducing eye strain.​
