Lens Transmission Data

In ophthalmology, high-energy visible light (HEV light) is high-frequency, high-energy light in the violet/blue band from 400 to 500 nm in the visible spectrum.  HEV light has been implicated as a cause of age-related macular degeneration. -wikipedia.org

Light Transmission Wavelengths (nm = nanometers)

ULTRAVIOLET RANGE: UVC= 100-280 nm | UVB= 280-315 nm | UVA= 315-400 nm

HIGH ENERGY VISIBLE RANGE: violet = 380-450 nm | blue = 450-495 nm

green = 495-570 nm | yellow = 570-590 nm| orange = 590-620 nm| red = 620-750 nm


Apples to Apples lens transmission testing data

We purchased and tested some of the leading computer gaming eyewear, eye fatigue eyeglasses and anti blue light glasses in the marketplace. We compared them to our lenses performance and had remarkable results. We release full disclosure of the data to the public.

UV = Ultraviolet | VIS = Visible Light | HEV= High Energy Visible | EMI = Electro Magnetic Interference | PL= Violet | BL = Blue | VL = Visible Light | Trans = Transmission | nm = Nanometers

*NOTE: Our data may differ from other spectrophotometer readings in different labs and the results may or may not be 100% scientifically accurate. We measure 3 specific visible light wavelengths PL395nm, BL460nm, VL550mn and the entire UV spectrum 200nm-400nm with the same analytical instruments. Our data measured is averaged and the results are compared to other computer eyeglass lenses in the market.
