The invention relates to eyewear and lenses for controlling and/or blocking the absorption of particular bandwidths of light that can impact the physiology of the wearer. The eyewear lens is adapted to selectively permit the relatively greatest percentage of a light within a wavelength range of between about 400 and 490 nanometers. The eyewear lens selectively permits the passage of light of the given wavelength range over one or more subregions of the eyewear lens. The one or more subregions cover in total at most 25-50% of the lens. The peak transmission level within the range between about 400 and 490 nanometers is at least about 70% and the passage of light outside of the range between about 400 and 490 nanometers is less than about 70%.
