AMA Laboratories now offers a variety of testing services to measure the impact of blue light, visible light and infrared light. 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, according to AMA.
AMA’s 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.
Finally, a test method has been developed for evaluating the Infrared Protection Factor (IRPF) of topical skin care/sun care products. AMA notes that infrared radiation has long been considered harmless, however it has recently been identified as a major contributor to photodamage and photoaging.
