Students and Exams: How to Stay Focused Without Burning Out Your Eyes
Study and Focus
During exam season, your eyes work overtime: notes on screen, videos, late-night summaries. And sleep, which is when what you've studied truly sticks, is often the first thing to be sacrificed.
Studying better isn't always about studying more: it's also about taking care of the tools you use to study, starting with your eyesight and your rest.
Memory Consolidates During Sleep
During sleep, your brain reorganizes and cements what you learned during the day. Staying up all night in front of the screen to 'gain hours' often comes at a high cost: you arrive tired and remember less. Blue light at night also delays your sleep by inhibiting melatonin.
A good night's sleep before an exam can be worth more than an extra hour of exhausted cramming.
How to Protect Your Eyes During Long Study Sessions
- Apply the 20-20-20 rule to rest your focus.
- Properly light your desk; don't let the screen be the only light source.
- Take active breaks every hour.
- Use an intense filter for hours with more screen time.

An intense filter for long sessions and a maximum filter for when you study at night and want to protect your sleep.
