RE: Zurich Sunglasses?
I have Zurichs. They are my "yard work" glasses. 'Nuff said.
I have Serengeti Sienna "Drivers", photochromic, non-polarized. Coated lenses; anti reflective back of lens. SUPER filters on UVA and B, and I have "raccoon eyes" after the first spring practice session. ALso available in prescriptions. Dow Corning hardened glass, shatterproof, exceed the ANSI 'safety glass' standard. Worth looking into.
THEN I find - at Wally World - in the Sporting goods section..... Remington "shooters", in a package with FOUR different color lenses, optically as near-perfect as one could want, a rigid case, strap, and they are "wrap around", so there's good protection on the sides and bottom edges. $8.00. They also stop UVA and B.
Lots of options out there; amazing, really.
