2. Understanding Blue Light (Recap + Deeper Science)
- Naučna objašnjenja (wavelengths, HEV light, retina penetration).
- Razlika između korisnog prirodnog plavog svjetla i štetnog vještačkog.
- Zašto je prirodno plavo svjetlo važno za budnost i raspoloženje.
3. Myths vs. Facts about Blue Light
- ❌ Myth 1: Blue light is the main cause of blindness.
✅ Fact: No strong evidence links normal screen exposure directly to blindness. - ❌ Myth 2: Blue light glasses solve all eye problems.
✅ Fact: They help reduce strain but lifestyle changes are just as important. - ❌ Myth 3: Only young people/gamers need protection.
✅ Fact: Professionals, children, and seniors are equally at risk.
4. Short-Term Effects of Blue Light Exposure
- Digital eye strain: blurred vision, dryness, headaches.
- Sleep cycle disruption (melatonin suppression).
- Psychological fatigue (screen overload).
5. Long-Term Risks (Debated & Under Research)
- Macular degeneration connection (what studies say).
- Possible retinal stress from cumulative exposure.
- Mental health and circadian rhythm effects.
6. Proven Strategies for Protection (Advanced)
- Device settings (Night Shift, Night Light, True Tone, f.lux, Iris).
- Screen filters (hardware & software).
- Blue light glasses – new generations with anti-glare + UV filters.
- Ergonomic adjustments (screen height, brightness, ambient lighting).
- Nutrition & lifestyle (lutein, zeaxanthin, omega-3).
- Digital detox habits – setting screen-free hours.
7. Blue Light and Specific Groups
- Children & Teens – effects on learning, concentration, and sleep.
- Remote Workers & Students – screen time skyrocketed post-pandemic.
- Gamers – extended exposure, late-night sessions.
- Seniors – added risk with aging retina + existing conditions.
8. Role of Employers & Schools in Blue Light Protection
- Companies providing wellness programs & blue light filters.
- Schools integrating digital safety in e-learning.
9. Practical Daily Habits Checklist
- 20-20-20 rule
- Hydration & blinking awareness
- Avoiding screens 2h before sleep
- Proper indoor lighting
10. Future of Blue Light Research & Technology
- New display technologies (OLED, e-ink, low blue light monitors).
- Smart glasses & AI screen filters.
- Ongoing medical studies – separating myth from evidence.
11. Conclusion
Blue light isn’t inherently evil — it’s about balance, awareness, and smart habits. Protect your vision today to enjoy healthy eyes tomorrow.”
