Test

Blue Light, also known as High Energy Visible Light (380-530nm), testing method designates protection capabilities via in-house generated High Energy Visible Light Protection Factor (HEV-PF) calculated from spectrometric measurements performed over the 380-530nm spectral range.

Visible Light (400-700nm) testing method designates protection capabilities via in-house generated Visible Light Protection Factor (VIS-PF) calculated from spectrometric measurements performed over the 400-700nm spectral range.
