The new 580P lens is a super lightweight, impact resistant polycarbonate alternative to glass. This Costa 580P lens features C-WALL - a highly specialized, oleophobic and hydrophobic coating to make it as virtually scratch resistant as glass, while also repelling water, oil and dust. All of the 580 lenses block yellow light at 580 nanometers on the light spectrum. Translation: you get incredible visual clarity, the highest level of polarization possible, and razor sharp color enhancement
