Kaenon is known for their impressive polarized sunglasses and SR-91 lenses. This new Kaenon Eyeglasses collection is just as impressive. Kaenon frames are extremely lightweight and comfortable. Their collection is built around four easy-to-wear styles in 6 hand-painted colors. Prescription lenses for these Kaenon eyeglasses are available with Shamir Autograph 2 Freeform Digital prescription lenses. You can select the new Trivex lens material to get the clarity and ABBE Value of the Kaenon SR-91 lens. Standard lens surfacing is also available for people who want to spend a bit less. Even our standard lenses are surfaced using digital equipment. But if the input isn’t digital we refer to the lens as “Non digitalâ€.
