Costa Del Mar BL 10 OAP Costa Del Mar Blackfin Plastic Sunglasses are oversize Rx-able rectangular nylon sport wraps with polarized polycarbonate lenses. The Blackfin is designed with corrosion-resistant stainless steel hinges, adjustable wire core temples and special materials on the saddle nose bridge and temples to ensure comfort and minimize slippage. The Costa Del Mar logo is engraved on the temples. These Costa Del Mar Sunglasses have lightweight polarized polycarbonate lenses that provide amazing clarity and 100% UV protection, shielding eyes from damaging UV (ultraviolet) radiation and reduce disabling or blinding surface glare. This makes them particularly useful for boating, driving, and other outdoor activities.
Co-injected into these lightweight nylon frames is a high-traction Hydrolite liner that holds tight no matter how hard you jostle your face while paddling or loading your kayak. Costa even made these expedition-ready sunglasses a little wider to reduce peripheral sun leakage that diminishes your vision.
The amber lenses enhance vision by blocking the somewhat hazy, blue end of the color spectrum, which results in greater contrast and improved depth perception. Wearers report crisper vision and increased ability to discern shapes, too, especially against green and blue backgrounds. They aid in discerning fish and underwater structures while sight-fishing in relatively shallow water. This is a good choice if you're going to be out in low-light conditions or on a day with changing weather patterns.
