The Smith Hudson Polarized sunglasses are lightweight and styled to fit the hip life. Carbonic lenses block 100 of UV rays, and wont shatter on you should you take a spill in whatever extreme sport you happen to be involved with when you wear them. The polarization reduces 99 of reflected glare, which enhances visual acuity and reduces eye fatigue. A smooth silver S logo adorns the sides of these shades, subtle, but noticeable enough to clue people into what style youre sporting. This model has a Grilamid nylon frame which is rugged, resilient, strong, flexible, lightweight and retains its shape.
