Blue Light Protection Factor (BLPF)
Just how Sun Protection Factor (SPF) measures protection for the skin, the BLPF scale measures lens protection for the eye. The higher the number, the better.
Amber BLPF 65 - GUNNAR's signature lens offers the optimal protection and performance.
Clear BLPF 35 - For discreet protection without the amber tint.
Sun BLPF 90 - For protection from digital screens in sunlit environments. Filters 100% UVA & UVB.
Amber Max BLPF 98 - Max protection for those who are highly sensitive or working at night.
