Re: Favorite Polarized Sunglasses?
Costa for me. Durable and a great warranty, but more importantly they have top shelf polarization and clarity in a wide range of lens colors and frames. Plus they're designed specifically for fishing.
To answer the specific question, green mirror, silver mirror, amber, vermillion, and copper are all amber-based lenses in Costa's line-up, meaning they will all increase contrast especially with green and browns. Green mirror is my all around fav. It blocks 2% more light than the others listed. For pure low-light use, amber, vermillion or copper are the best choices for light transmission. CL
