What is 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 against artificial blue light. The higher the number, the better.
Clear BLPF 35 - For discreet protection without the amber tint
Amber BLPF 65 - For optimal protection and performance
Sun BLPF 90 - For protection from digital screens in sunlit environments
Amber Max BLPF 98 - Max protection for those who are highly sensitive or working at night
