Digital Eye Strain and Computer Vision Syndrome (Statistics)
Computer vision syndrome, also known as digital eye strain, is the combination of eye and vision problems associated with the use of computers and other electronic devices. A research paper says, many individuals spend 10 or more hours per day viewing these displays.
How about you, have you ever experienced any of the following, while working or being in front of a computer screen?
- difficulty in focusing
- neck pain

- a headache
What causes eye strain and blurred vision?
The most common factors of Computer Vision Syndrome (CVS) or Digital Eye Strain are:
- Poor lighting
- Glare on a digital screen
- Improper viewing distances
- Poor seating posture
- Uncorrected vision problems
individually or in many cases a combination of these factors. The combination gets even worse when you sit in front of a computer screen for a long time while wearing contact lenses.
MSNBC reports: "Studies have shown that when people are working on a computer, their rate of blinking goes down by two-thirds, which can result in dry, stinging eyes. This is especially a problem for contact-lens wearers, who already are at risk for dry eyes, so doctors recommend they use lubrication drops.

Here are, 5 tips for relief of eye strain/computer vision syndrome
- 1. Keep the correct distance.
As with driving – keeping a safe distance, it's the best practice. For example, when reading (on your computer, phone or tablet), make sure the text is always at least 30–40 cm away.
- 2. Proper lighting.
When focusing on an object, try to position the light in a way that does not create a shadow. Shadows can tire vision. For example, you can adjust the brightness and contrast of a computer or TV screen to your personal needs to relieve your eyes.
- 3. The 20–20–20 rule.
Every 20 minutes, take a 20-second break, looking 20 feet away. The best practice is to have at least two short breaks per hour (30 to 60 seconds is enough). Every two hours take a 15 minutes break.
- 4. New examination
Your vision performance is constantly changing and it is very likely that the glasses or contact lenses you wear are no longer suitable. Take a new exam, you may need different grades or a different kind of contacts.
- 5. Get down to Earth.
Tension and abnormal posture can have a negative impact on your vision but most importantly on your body. Make sure your feet always touch the floor, firmly.
