Do the crystalline glasses have a magenta hue?
We use an Anti-Reflective (AR) coating to increase light transmission through the lens allowing for brighter, crisper image detail. We tune our AR coating and select a center for peak reflectance over certain parts of the spectrum. Our Amber tint has peak reflectance at 450nm which corresponds with 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 reflect closer to 550nm (green), hence you may perceive a slight green on the lens (less than 1% reflectance). The 550nm peak reflectance counters the results of the natural filtering from our lens material. The result is an equalized balance of light allowing for the truest color necessary for design applications.
