The Oakley Straightlink Prizm Sunglasses offer a bold, rectangular design and cutting-edge optics for your outdoor lifestyle. Taking design cues from Oakley's Straight Jacket and Chain Link Sunglasses, the Straightlink plays off both frames for a thoroughly modern vibe. The O-Matter frame keeps it exceptionally lightweight and durable. Unobtainium nose pads and earsocks keep the frame secure during fast-paced activities. Prizm lens technology offers a high-definition boost of visual acuity in a wide variety of light conditions. Oakley does this by filtering out unwanted visual noise while boosting parts of the visible spectrum that your eyes are most sensitive to. Ultimately, this results in precise clarity without washed-out vision on those bright, sunny days. Going one step further to protect your eyes from harmful glare, Oakley's HD Polarization filters out 99% of glare to keep it from fatiguing your eyes in bright outdoor environments. The Plutonite lens is crafted from impact-resistant polycarbonate for a lightweight feel that's durable enough for your high-octane lifestyle.
