I thought it was to keep the bugs away. hahaha
I understand the point of yellow and amber lenses is to filter out the portions of the blue spectrum which doesn't do it for us humans (spexx, weigh in here?) and they are mostly effective at twilight or on overcast days.
I'm thinking overcast days must have more blue light (higher color temp. I'll look that up) and by filtering it out things seems brighter because we see blue light as darker?
maybe?
They increase the contrast and that alone takes strain off the eyes. In B&W photography those color lenses help to render the sky a darker shade of gray since B&W film is somewhat more blue sensitive than our eyes.
