Maui Jim Hot Sands Polarized Sunglasses combine durability, comfortable wear and a contemporary sport design for active lifestyles. Color-enhancing, glare-fighting PolarizedPlus2 lens technology eliminates 99.9% of glare and blocks 100% of UV rays. Lenses are also impact- and scratch-resistant. Grilamid frame is lightweight and form fitting. High-Contrast Lenses (HCL) work great on overcast or foggy days. Neutral Gray lenses are best in bright, direct sunlight. Maui High-Transmission (HT) work best in early mornings, late afternoon and foggy days as the lenses will heighten contrast and depth of field so that low light is perceived with new vibrancy. The Skin Cancer Foundation recommends this product as an effective UV filter for the eyes and surrounding skin. Color: Gray.
