Computer Vision Syndrome: How to Avoid Eye Strain

Currently, we spend more than 7 hours a day in front of a screen. Whether at work, school, or simply while commuting, our eyes are exposed to constant work. This has led to what is known as Computer Vision Syndrome (CVS): a series of visual discomforts linked to the widespread use of digital devices. But what exactly does this syndrome represent, and how can we prevent its onset?

What is Computer Vision Syndrome?

SVI is a series of visual and ocular symptoms that arise after constant use of screens. Its main manifestations include:

• Dry eyes
• Blurred vision
• Headache
• Light sensitivity
• Eye fatigue
• Itching or burning

This syndrome affects individuals of any age, but is especially common in office workers, students, and anyone who spends several hours a day using a computer, mobile device, or tablet.

Main causes of SVI

Computer Vision Syndrome does not arise for a single reason, but due to a combination of factors.

• Flicker reduction : When we focus on a screen, flickering is reduced by up to 60% less than usual.
• Poor lighting : poorly adjusted reflections or contrasts cause visual fatigue.
• Body position : Maintaining an incorrect posture can strain your eyes.
• Screen angle and distance : Proximity or forced tilt also have an impact.

Consequences of not treating it

Ignoring SVI can lead to permanent discomfort:

• Concentration problems
• Difficulty sleeping due to exposure to blue light
• Increased dryness in the eyes

• Decreased work performance

5 keys to preventing Computer Vision Syndrome

1. Apply the 20-20-20 rule . Every 20 minutes, look at an object 6 meters (20 feet) away for 20 seconds. It's a simple technique to relax your eyes.
   
2. Transform your workplace. Avoid direct reflections, adjust your screen brightness, and apply filters if needed.
3. Take active breaks to blink more and maintain eye hydration.
4. Use artificial tears to hydrate your eyes; they help combat dryness caused by lack of blinking (see our previous article on how to use them properly).

Contact lenses and screens: essential recommendations

If you wear contact lenses and work with screens for hours, keep in mind:

• Choose lenses that breathe and provide great hydration, such as our HydroPlus or HighOxygen ranges.
• It is preferable not to go to bed with them on.
• If you experience discomfort after several hours, you should remove them and rest your eyes.

Conclusion

Computer Vision Syndrome is becoming more common, but it's also easy to prevent. Protecting your eye health in the digital age is essential, especially if you wear glasses.
