Scrolling through your phone in bed with the lights off is something many people do. But can this habit actually harm your eyes?
The good news is that there is no convincing evidence that using your phone in the dark causes permanent eye damage.
However, staring at a screen for long periods can lead to temporary eye strain, dryness, and discomfort.
Why Do Your Eyes Feel Tired?
When you're focused on your phone, you tend to blink less than usual. This can cause tears to evaporate more quickly, leaving your eyes feeling dry or irritated.
A bright screen in an otherwise dark room can also make your eyes feel uncomfortable, particularly when you're using your phone for an extended period.
Can Using Your Phone at Night Affect Your Sleep?
Using your phone right before bedtime can make it harder to fall asleep. Light from screens, particularly in the evening, can interfere with melatonin production, the hormone that helps regulate your sleep-wake cycle.
Tips for Using Your Phone More Comfortably
A few simple changes can make a difference when using your phone at night:
- Keep a soft light on rather than using your phone in complete darkness
- Adjust your screen brightness to match the lighting around you
- Take regular breaks and remember to blink
- Try to avoid screen time for 1–2 hours before bedtime
Using your phone in the dark doesn't mean you're damaging your eyes. Still, being mindful of your screen habits can help reduce eye strain and keep your eyes more comfortable throughout the day.
