Some people think that yellow gives you better visual acuity and clarity without making anything standing in the shadows appear darker as sunglasses can do.
Welcome to the site! I sometimes will wear yellow lenses on a cloudy day instead of sunglasses just to keep something there to protect my eyes from brush. Todd wears a pair of yellow lenses on the show that are actually corrective lenses.
I've never tried this myself but it makes sense. I wear orange and yellow polarized lenses while fishing for the same reasons. The only reason I haven't tried this is because I hate shooting with glasses on.
I had bought a pair of Oakleys and they had an amber "outdoor" lense, I feel like the amber color made things more clear and movement was easier to see.
I think they help eliminate the shadow effect in the woods. I do wear them occasionally, mainly during gun season.
