1. A sunglass lens comprising a filter, wherein the sunglass lens transmits 350 lux or more, 400 lux or more, or 500 lux or more, of light intensity within a range of light wavelengths having a 45% or greater light transmission through the sunglass lens, wherein the range of light wavelengths cover a majority of absorption curves or spectra of melanopsin and rhodopsin and also partially cover absorption curves or spectra of at least some opsins of an eye's cones, wherein the sunglass lens provides an overall visible light transmission through the sunglass lens of 3% to 18%, and wherein the sunglass lens provides blended color balance transmission of light wavelengths, thereby allowing the sunglass lens to pass or otherwise satisfy the International Organization for Standardization (ISO) and/or American National Standards Institute (ANSI) sunglass traffic light test(s).
