From Eschenbach:
Ambelis Eyewear features amber lenses that protect the eyes by blocking light 470nm in wavelength and less, cutting out most blue light. The attractive frame provides protection, comfort, and style as well as side and top protection. The protection comes from shields on the top and bottom of the lens as well as from a custom made side shields. Although providing excellent, full coverage, the shields still allow air to circulate freely avoiding the fogging-up effect that can occur with more snug fitting eyewear.
"Off-the-shelf" options are available in 5 tints: 15 Light Amber, 50/15 Gradient Amber, 65 Dark Amber, 75P Darker Amber Polarized, and 85 Darkest Amber. These tints give users a choice in how much overall light they wish to have blocked, and the gradient option provides the ability to block more light looking straight ahead, and less light when looking down.
