Blue Light Blocking

What is Blue Light Blocking?

Wearing amber-tinted glasses in the evening to block blue light that suppresses melatonin production. Substantial evidence for reducing sleep onset latency in people with sleep disorders, shift workers, and jet lag — mixed evidence for healthy adults.

Is there evidence for it?

How do you do Blue Light Blocking?

1. 1.Wear amber/orange-tinted blue-blocking glasses for 2-3 hours before bedtime
2. 2.Choose glasses that block light in the 400-500nm range (not just marketed as 'blue light blocking')
3. 3.Enable Night Shift/Night Mode on all screens after sunset as an additional measure
4. 4.Dim overhead lights in the evening — switch to warm-toned, low-wattage lighting
5. 5.Combine with reduced screen time overall for maximum effect — glasses alone aren't sufficient

How long does it take?

0 hours extra (just wear glasses during normal evening activities).

Is it hard to start?

easy.
