Extremely comfortable to wear, Wiley-X ALFA features a lightweight, elegant rectangular frame. It features removable pivoting side shields for extra peripheral protection when you need it. The Blue Mirror polarized lens is ideal for sea and deep-water fishing, as well as for bright days. The Captivate by Wiley X range of eyewear helps protect your eyes from damage during outdoor activities. The wrap-around frame and ANSI-approved lenses will protect you from the unexpected. Polarized lenses filter out eye-damaging rays, reduce glare by dramatically reducing reverberation, and help you see what's going on beneath the surface of the water. WX polarized lenses offer 100% UV protection and feature a hydrophobic, anti-reflective coating protected by scratch-resistant coatings.
