Our overall darkest lens is Fusion.
If you are looking for the darkest non-mirrored lens, that is Fuse +Plus grey polarized.
Each listing on our site will have a category number that refers to the darkness of the lens. Most Fuse Lenses will fall under Category 3, which are suitable in strong sunlight or for extended outdoor wear. It is also good to note that the darkness of the lens does not correspond to the protection level. All Fuse Lenses are 100% UV protected!
