Do the crystalline glasses have a magenta hue?
We use an Anti-Reflective (AR) coating to increase light transmission through the lens allowing for bright and crisper image detail. We tune our AR coating and select a center for peak reflectance over a certain parts of the spectrum. Our Amber tint has peak reflectance at 450nm which corresponds to the increased spike of energy in the blue part of the spectrum from digital screens, reducing strain on the eyes.
For our Crystalline Lens, we tune the AR coating to reflects closer to 550nm (green). Hence, you may perceive a slight green on the lens (less than 1% reflectance). The 550nm peak reflectance counters the natural filtering resulting from our lens material. The result is an equalized balance of light allowing for truest color necessary for design applications.
