The 20&20 model is our signature line and couples polarized polycarbonate lenses with a durable, lightweight, BPA-free memory frame.
The frames are an injection molded thermoplastic memory polymer that can be put under extreme pressure and still return to its original shape. It is amazingly light, not degraded by UV wavelengths or human sweat, and is BPA and EA free. The lens begins with a polarized polycarbonate core, which is then thermally fused to four additional layers. Two UV filters block 100% of UVA and UVB ultraviolet rays up to 400 nanometers.
