Thirty seconds of science

How it works

01
Screens flood your eyes with blue light

Laptops, phones and LEDs peak in the 400–500nm band — the range tied to strain and disrupted sleep.

02
The tint absorbs it before it reaches you

Color is the filter. Yellow takes 89%, orange 96%+, red 99% — measured, not marketed.

03
Headaches gone. Sleep recovered.

Your eyes relax by day, and your melatonin stays untouched at night. You feel the difference in a week.

Don’t take our word for it.
Independently tested to BS EN ISO 12312-1 — the full lab reports are public.
