Yes, every pair of Costa sunglasses features polarized lenses to cut glare from reflective surfaces like water, whether you choose the glass or polycarbonate version of the 580 lens. That consistent polarization is central to Costa's reputation as a performance eyewear brand.
Yes, Costa makes prescription 580 lenses for sunglasses, with single-vision options available across the entire sunglasses line, plus Costa's Waypoint digital lens technology for select single-vision and progressive prescriptions.

All authentic Costa lenses are etched with a distinct marking that verifies authenticity, and FramesDirect, as an authorized retailer, sells only guaranteed genuine Costa eyewear. If you ever need replacement lenses, authentic Costa replacement lenses are available for all Costa eyewear models.
Costa's 580 lens technology uses a polarized film layer that filters out yellow light, which typically distorts clarity and contrast, while blocking blue light to reduce haze. The lenses are available in glass (marked with a G after the model number) or polycarbonate (marked with a P), with glass offering the sharpest clarity and best scratch resistance.
Costa sunglasses were invented in 1983 by fishermen who wanted eyewear tough enough to handle the harsh conditions of a salty sea environment. That origin, formerly under the name Costa Del Mar, is why the brand remains the go-to choice for people who spend serious time on or near the water.
