Oakley Goggles Snow L Frame OTG If you wear prescription eyewear, you have something in common with the mountain’s top athletes. Not everyone is born with perfect eyes, but those who refuse to compromise on vision can get the clarity of Oakley optics with the compatibility of the L FRAME goggles. Designed to allow room for prescription glasses, the comfortable fit takes advantage of double-layer face foam and durable urethane that maintains flexibility when the mercury plummets. F-2 series anti-fog treatment is matched with a vented dual lens of optically pure LEXAN®. The Persimmon lens color boosts contrast to improve depth perception in low light and overcast/flat light.
