Computer vision syndrome (CVS), also known as digital eye strain, affects millions of people who use digital devices daily. It causes a range of symptoms such as eye strain, blurry vision, and neck pain. Understanding its causes and how to prevent it can protect your eyes in the long run.
At SpecSMART Eye Clinic Ikeja, we see many patients affected by the growing demands of screen use. Our experienced optometrists are trained to detect early signs of CVS and recommend practical solutions for long-term relief.
What is Computer Vision Syndrome?
Computer vision syndrome is a group of eye- and posture-related problems caused by prolonged use of digital screens—laptops, phones, tablets, and desktops. While it primarily affects the eyes, it can also cause discomfort in other areas like the neck and back. This condition affects both children and adults who spend long hours in front of screens without breaks or proper setup.
Symptoms of Computer Vision Syndrome
If you spend a lot of time on digital devices and experience any of the following, you may be dealing with CVS:
-
Blurry vision
-
Eye strain and fatigue
-
Headaches
-
Dry or irritated eyes
-
Eye pain
-
Neck and shoulder pain
-
Lower back pain
Our optometrists at SpecSMART Eye Clinic Ikeja often diagnose CVS based on a combination of these symptoms and lifestyle patterns. Early detection is key to preventing long-term discomfort.
Causes of Computer Vision Syndrome
Several factors contribute to digital eye strain:
Glare and Poor Lighting
Glare from the screen or nearby light sources forces your eyes to work harder, increasing fatigue.
Small Text and Fonts
Straining to read small or low-contrast text puts extra tension on the eyes.
Poor Posture
Improper seating or desk setup leads to physical strain in the neck, shoulders, and back.
Reduced Blinking
People tend to blink less when using screens, which leads to dry, irritated eyes.
Uncorrected Vision
Using an outdated prescription or avoiding glasses when needed contributes to CVS symptoms. This is a common issue our optometrists address during digital eye exams at SpecSMART Eye Clinic Ikeja.
Age-Related Factors
People over 40 may develop presbyopia, making near tasks like reading on screens harder without the right corrective lenses.
How to Prevent and Manage Computer Vision Syndrome
Our optometrists at SpecSMART Eye Clinic Ikeja recommend the following proven methods to reduce CVS:
Screen Adjustments
-
Keep your screen 20–28 inches from your eyes
-
Position the monitor just below eye level
-
Use larger fonts and increase display contrast
Glare Control
-
Install anti-glare screen filters
-
Adjust room lighting to reduce screen reflection
-
Use anti-reflective lenses if recommended by your optometrist
Posture Correction
-
Sit with your feet flat and back straight
-
Keep arms bent at a 90-degree angle
-
Use a document holder beside your screen to reduce neck strain
Eye Drops and Breaks
-
Use lubricating eye drops for dryness
-
Follow the 20-20-20 rule: every 20 minutes, look 20 feet away for 20 seconds
Corrective Lenses
-
Ensure your prescription is up to date
-
