The Men's Oakley Twitch sunglasses: No matter how much technology they pour into a frame, Oakley's science has to be a work of art. Thatâ⠬⠢s how the unbeatable clarity of HIGH DEFINITION OPTICSà ® (HDOà ®) became the hard angles and jagged edgework of TWITCHââ ¢. Enhanced with dual cam hinges and metal Oakley insignias, the lightweight O MATTERà ® frame combines comfort with durability. Protection includes 100% filtering of all UV plus impact resistance that meets all ANSI Z87.1 standards. And the authentic styling is just as aggressive as the technology.
