Millions of people could be unknowingly risking permanent damage to their eyes due to excessive screen time, experts warn. A new study highlights the dangers of prolonged exposure to digital devices, which may lead to irreversible vision problems.
The Hidden Danger of Screens
Optometrists are raising the alarm over the long-term effects of blue light emitted from smartphones, computers, and tablets. Extended use can cause digital eye strain, dry eyes, and even contribute to macular degeneration—a leading cause of blindness.
Symptoms You Shouldn't Ignore
Common signs of eye strain include:
- Blurred vision
- Headaches
- Dry or irritated eyes
- Difficulty focusing
- Neck and shoulder pain
How to Protect Your Vision
The NHS recommends the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. Other protective measures include:
- Using blue light filters on devices
- Adjusting screen brightness to match surroundings
- Taking regular breaks from screens
- Ensuring proper lighting in work areas
With remote work and digital entertainment on the rise, experts urge the public to take these warnings seriously before permanent damage occurs.
