Designed for gamers and available without a prescription, oakley’s proprietary prizm gaming™ 2. 0 lens technology has been developed for oled & led displays. It reduces blue light with minimal color shift while reducing glare from screens and providing sharp visual acuity. Uniquely optimized to attenuate light from oled and led screens to reduce blue light exposure emitted from the newest of screens, it helps eyes stay comfortable during long gaming sessions and it is engineered with specific oakley lens designs that help you see more clearly. Regarding its blue light filtering properties, prizm gaming™ 2. 0 filters 30% led blue light (400-500nm). The iconic silhouette of one of oakley®'s bestsellers holbrook™ is re-engineered to properly fit smaller faces. Without sacrificing performance features or style, this youth version of an adult style features performance features like prizm™ lens technology and stylish accents like metal rivets and a keyhole bridge.
