Blue Light: A Silent Danger
We spend an average of 10 hours a day in front of screens. Phones, computers, tablets... all emit high-energy blue light (HEV) that penetrates deep into the retina and can, over time, cause eye strain, sleep disturbances, and cellular damage.
Symptoms of Overexposure
- Eye Strain: dry eyes, burning, gritty sensation
- Headaches: tension headaches at the end of a screen day
- Sleep Disorders: blue light blocks melatonin
- Blurry Vision: difficulty maintaining focus
5 Tips to Protect Your Eyes
1. The 20-20-20 Rule
Every 20 minutes, look at an object 20 feet (6 meters) away for 20 seconds. Simple, effective.
2. Adjust Your Screen Brightness
Lower the brightness in the evening and enable “Night Shift” or “Blue Light Filter” mode on your devices.
3. Maintain a Correct Distance
Your screen should be at least 50-70 cm away from your eyes.
4. Blink Regularly
In front of a screen, we blink 3 times less than usual. Keep that in mind!
5. Choose Glasses with Integrated Filter
This is where Joey Cyan BlueCut makes all the difference. Our optical lenses incorporate a certified anti-blue light treatment that filters up to 40% of harmful wavelengths without altering color perception.
