My Workbench FineWoodworking Sat Sunglasses Green. The Sat sunglasses feature a cat eye frame with a geometric shape. The milled details on the front and the temples, together with the signature Woodys wood inlay at the tips, give it a sophisticated look. German 5 axis hinges provide strength and ergonomics. The CR39 lenses, produced by Carl Zeiss, offer maximum protection against UVB and UVA rays, as well as visual comfort.
