Costa combines blended bifocal lenses and tints tailored to adventure in the C-Mates bifocal sun eyewear collection. Costa's patented lens technology and rugged sunglasses frames are available with bifocal lenses in magnifications from +1.50 to +2.50. This 100% UV protective, polarized reading eyewear also shields your eyes from the sun's UV rays and blocks harsh glare for more comfort on the water or behind the wheel.
Costa digital lens technology ensures distortion-free lenses in the reading power of your choice. Patented Costa 580P lenses are rugged and shatterproof, engineered to withstand the adventures that come with active lifestyles. Reading lenses feature gradual magnification: these bifocals have no visible line.
Find your favorite Costa sunglasses frames styles with bifocal reading lenses to get top-quality sun protection and better vision outdoors. Full-rim TR 90 nylon frames are plenty rugged, and many styles feature a patented venting system to reduce fogging for more comfort. Costa frames withstand wear and tear, and flexible hinges offer a comfortable, slip-free fit. For nearly weightless sunglasses, reach for the rimless C-Mates bifocal styles. Less frame material means lighter weight, so you'll barely know they're there.
Patented Costa lens technology provides crisp, clear vision on the water or off, and a range of lens colors tailors your vision even further. Anglers prefer lenses designed for use on the water: blue and green lenses with mirror finish block harsh glare, intense light, and UV rays while fine-tuning contrast and color for improved clarity. Gray reading lenses are ideal for everyday wear, and versatile copper lenses are suitable for varying light conditions or cloudy days. Choose a mirrored lens coating for the most light-blocking power available in Costa reading sunglasses. As an authorized retailer, FramesDirect sells only guaranteed authentic Costa C-Mates bifocal readers sunglasses.
