Costa Lens Technology
Costa’s 580 lens technology was specifically developed to enhance colors in outdoor environments and produce stunning clarity in prescription sunglass lenses. This technology effectively absorbs high energy blue light (HEV) and filters out harsh yellow light which occurs at 580 nm on the visible light spectrum. The result is a lens that naturally boosts the reds, greens and blues in the spectrum and greatly enhances colors and contrast.
The 580 technology is available in three lens materials, Lightwave Glass, Trivex and Polycarbonate and all three are offered in single vision as well as progressive prescription lenses.
When selecting a lens material for Costa prescription lenses, it's important to understand the difference between the 580G Lightwave Glass and the 580P Polycarbonate or Trivex lenses.
In general, the Lightwave Glass lenses offer slightly better clarity and are more scratch resistant than either the Trivex or Polycarbonate lenses. On the flip side, the Trivex and Polycarbonate lenses will be lighter than the Lightwave Glass and also offer excellent impact resistance. Additionally, all three materials feature Costa's innovative C-Wall coating, which actively repells oils, water and dust.
In our opinion, it's a toss up. It's hard to beat the clarity of the 580G lenses, but if you need shatter resistance or the weight of glass isn't appealing to you, then the 580P lenses offer industry best clarity and contrast in a Polycarbonate or Trivex lens.
* Costa 580G Lightwave Glass prescription lenses are currently available in about 75% of Costa frame styles. The 580P Trivex or 580P Polycarbonate prescription lenses are available in all Costa frame styles.
