Smith gave the Polarized Guides Choice Sunglasses fishing-friendly features and a casual design so you can wear them off the river too. The water-specific, scratch-resistant Techlite polarized glass TLT lenses use Tapered Lens Technology to straighten out oncoming rays for 100% accuracy and comfort. Smith added hydroleophobic and anti-reflective coatings to resist water, smudges, and reflections. The frame features lightweight Evolve material, a wraparound eight base curvature, rust-resistant stainless steel spring hinges, and hydrophilic nose and temple pads for a secure grip. .
