This is a promotional video for Zeiss Sonar lenses, and it explains interesting science on the light spectrum and eye color perception. I have some Teton Gravity Research goggles with Zeiss Sonar lenses coming in the mail...I'll give them a look-through on some dark gray rain clouds before I have a chance to get to snow.
I was very pleased with my Dragon Lumalens goggles until...(a) the strap lost its stretch, and they don't sell replacements, (b) stored in the box over the summer the light lens darkened. Now the dim day and sunny day lenses are about the same density. Weird.
