A 35-year-old man shocked doctors when he suddenly lost vision in one eye — and the reason behind it is a warning for everyone.
What happened?
The man, otherwise healthy, began experiencing blurry vision and eventually complete blindness in one eye. After several tests, doctors found no injury or underlying disease. But when they investigated his daily habits, one pattern stood out — he had a habit of using his phone in bed every night with one eye closed.
The real danger: Temporary Smartphone-Induced Blindness
Medical professionals now recognize this condition, where people experience temporary or even prolonged vision loss due to staring at bright screens in the dark with only one eye. When you lie on your side and scroll with one eye blocked (by a pillow or just naturally closed), the exposed eye adjusts to the bright screen while the closed eye remains in darkness. When both eyes are finally used again, there’s a mismatch that can result in vision disturbance — or in extreme cases like this one, even serious damage.
How does it affect your eyes?
- Causes eye strain and fatigue
- Disrupts your circadian rhythm and sleep quality
- May lead to retinal stress or optic nerve issues
- Increases risk of digital eye syndrome
- Can cause temporary or lasting vision impairment
Preventive tips for screen users at night:
- Use night mode or blue light filters
- Always keep both eyes open while looking at screens
- Avoid using phones in complete darkness
- Take breaks every 20 minutes (20-20-20 rule)
- Use warm light instead of cool, bright light at night
Bottom line: A simple habit — like checking your phone in the dark before sleeping — might seem harmless but can have serious long-term consequences. Protect your eyes. Light matters more than you think. 👓📵
