What is eye strain?
Eye strain, also known as visual fatigue or asthenopia, occurs when we overuse our eyes, especially when working on a screen. It results in fatigue of the ciliary muscle, responsible for focusing, which leads to blurred vision, discomfort, and other symptoms.
👉 To limit these inconveniences, it is often recommended to wear anti-blue light glasses, specially designed to reduce visual discomfort linked to screens.
Symptoms of Eye Strain at Work
When returning from vacation, suddenly going from days outdoors to 6 or 8 hours in front of a screen can cause:
- Blurred or double vision after prolonged concentration,
- Tingling, dryness, redness or watery eyes,
- Frequent headaches,
- Sensitivity to light,
- Difficulty staying focused.
These discomforts appear gradually but can become disabling if they are not taken into account.

Digital Eye Strain
With the development of teleworking and digital tools, screen vision syndrome now affects a large majority of working people.
The main causes are:
- Reduced blinking: in front of a screen, we blink 5 times less often, which promotes dry eyes,
- Artificial blue light: it increases visual fatigue and disrupts sleep,
- Frozen posture: which accentuates cervical tension and migraines.
Eye strain or presbyopia: how to tell the difference?
Many people confuse eyestrain with presbyopia. However, they are two distinct phenomena:
Eye fatigue is temporary, due to visual overwork, and disappears with rest and adapted habits.
Presbyopia is an age-related visual disorder (from the age of 40 on average). The lens loses its flexibility, making near vision difficult, even when rested.

Solutions to reduce eye strain at the start of the school year
1. Apply the 20-20-20 rule
Every 20 minutes, look away from the screen and stare at an object 6 meters away for 20 seconds. This helps relax your eyes.
2. Optimize your workstation
- Screen 50-70 cm from the eyes, slightly below the gaze,
- Adapted brightness and reduction of reflections,
- Uniform ambient lighting (avoid strong contrasts).
3. Moisturize your eyes regularly
Remember to blink voluntarily and, if necessary, use artificial tears to compensate for dryness.
4. Wear suitable glasses
