Sunglasses Lenses

Lens Materials

Carbolite™ polymer lenses have 3-times the impact resistance of glass while weighing less than half the weight. When impacts are possible or unavoidable, this material is what you want to provide perception while protecting your eyes. Provides 100% protection from harmful UVA, B and C radiation. Created by a linking of polymers and carbonates, Carbolite™ is virtually indestructible. This is also the logical choice for any impact sport.

Lens base curvature:

Most plano(non-corrective)sunglass lenses are spherical in shape meaning the lens is the same curvature in all meridians. In optics, lens base curve is measured with a tool called a lens clock on the outside surface of the lens. A flat surface would be shown as zero. A lens clock is a mechanical dial caliper that is used to measure dioptric power of a lens. It is a specialized version of a spherometer. The greater the numeric value, the greater the curvature of the lens. In corrective optics the curvature between the inside and outside lens surfaces would be different and a calculation would determine the power of the lens. For sunglasses the curvatures are roughly the same inside and out and no power is introduced into the lens.

Coatings:

Tri-Oxide mirror coatings are multiple layers of metallic oxide coatings that selectively filter light. This allows us to use lighter density lens colors while still allowing squint free vision.
