Is Blue Light Blocker Worth It?
Yes, blue light blockers are worth it when used correctly. They reduce digital eye strain, support melatonin production at night, and help protect long-term eye health. However, effectiveness varies by usage, lens quality, and timing.
When Does Blue Light Blocking Actually Help?
If you spend more than 4–6 hours per day on digital screens—and experience dry eyes, fatigue, or poor sleep—blue light blocking glasses can offer noticeable relief.
- During prolonged screen use: Reduce glare and prevent digital eye fatigue.
- Before bed: Prevent blue light disruption to your natural sleep cycle.
- For older adults: Help filter short-wavelength light that can accelerate eye aging.
- In office or LED-lit environments: Improve contrast and reduce headaches.
