Digital eye strain: how to protect your eyes from computers, smartphones and LEDs
We spend over 8 hours a day in front of screens: computers, smartphones, tablets, TVs and LED lights. This digital lifestyle can cause eye strain, dry eyes, headaches and difficulty focusing. In this guide, we look at how digital vision works, what the most common symptoms are and what professional solutions are available from theIsolani Experience™ to protect the eyes and improve visual comfort.
1. What happens to our eyes when we use screens
Digital viewing requires constant effort. When we look at a screen:
- let’s wink less → dry eyes
- we maintain a fixed distance → accommodative fatigue
- Let’s focus our attention on the bright details → visual strain
- posture is affected → neck tension
Find out more about the technical concepts in the glossary dedicated to accommodation e convergence.
2. The most common symptoms of digital eye strain
The Digital Eye Strain (digital eye strain) can manifest as:
- eye irritation and dryness
- blurred vision
- headache
- difficulty focusing
- a feeling of heaviness in the eyes
- neck tension
3. Blue light: what it is and what it isn’t
Blue light is a natural component of visible light. Digital screens emit a small amount of it, but enough to contribute to eye strain. It is not harmful, but it can increase eye strain.
For further information, please refer to the glossary on blue light filter.

5. Practical tips for protecting your eyes
- The 20-20-20 rule: Every 20 minutes, look at an object 20 feet (6 metres) away for 20 seconds.
- Proper lighting: avoid excessive reflections and contrasts.
- Adequate distance: 50–70 cm from the monitor.
- Screen at eye level: reduces neck tension.
- Ambient humidity: helps to reduce dry eyes.
