FEATURES of the Native Blanca Polarized Sunglasses
Interchangeable Lens System
Co-Injected Molding: Native frames now seamlessly incorporate their grippy, comfortable molding right into the plastic
Rhyno-Tuff Air Frames: Made with proprietary high-performance thermoplastic material that is extremely lightweight, yet durable enough to withstand high-velocity collisions and temperature extremes
Cushinol: Cushinol nose pads ensure a soft feel and custom fit, regardless of nose shape or size, and Cushinol temple boots create a non-slip grip to keep sunglasses in place during athletic activity
Cam-Action Hinges: This patented feature allows the temple to quickly lock into position
Mastoid Temple Grip: This proprietary design feature ensures the temple ends hug the mastoid bone (behind your ears), allowing for a secure and comfortable fit
N3 Lens Technology: This is the most innovative and advanced polarized lens on the market. For real. N3 lenses block up to 4 times more infrared light than regular polarized lenses, pass Z87.1 testing, provide UV protection up to 400nm, and by significantly reducing blue light and selectively filtering UV, they deliver high contrast, crisp definition, and peak visual acuity.
I usually can wear sunglasses/sportglasses off the shelf. These were too wide and did not hug the temples at all resulting in flopping around in any kind of activity. I will be returning these and looking for a pair I can run, skate ski, ski, etc. in.
