You shouldn't have to sacrifice performance in your casual wear. Ryders Eyewear doesn't think so either, so it packed the stylish Serra Polarized Sunglasses with features from it's performance line into everyday shades. For starters, polarized lenses cut back on glare and provide high color contrasts for optical clarity. The lenses are also impact and scratch-resistant so you can really take them through the wringer without having to worry about ruining them. Keeping the lenses in place are the Grilamid frames. A Swiss technology, these frames are durable, extremely flexible, and lightweight for comfort throughout your day.
