SunDogs's premium PC Polarized sunglasses with Cristec Sub injection brand lenses offer crystal clear viewing without distortion. This brand of lenses are unique in that the PC material is injected into a lens mold containing the polarization filter. Lens stress comes from bending the flat polarized filter into a curved shape and forcing it into the sunglass frame. This stress can cause a "rainbow effect" that is less evident with Cristec Sub technology.
Cristec Sub lenses are extremely durable and impact resistant. This makes them the optimal choice for impact related activities where you need the benefit of polarized technology. SundDogs's PC Polarized lenses have a superior hard coating which will help avoid scratches. The frames are constructed with TR90, a superior plastic material with remarkable memory and flexibility.
SunDog PC Polarized sunglasses have an extremely high polarization efficiency of 99.7%
