What a 100 means for blue light glasses
Evening glasses judged on how much blue they actually block — a stated percentage, not a tint.
This score compares Swanwick Night Swannies against 14 other blue light glasses only. It is not comparable to a score in another category — a mattress and a sleep mask share no attribute, so a single ranking across them would be arithmetic without meaning.
How the score was reached
Function & Control
- 99% blue blocked
- Evening amber/red tint
- Targets melatonin onset
Verified & Non-Toxic
- FDA registered
Not declared
Swanwick publishes nothing about material & build, durability & care. These are left out of the score rather than scored as zero — silence is not evidence of a failing. They are why the score is capped at 90 for this product.
