Nike Max Transitions Show-X2, $199; nikegolf.com
Born of a partnership with Transitions Optical, Nike's new adaptive sunglasses include two polycarbonate lens options that respond to different light conditions. The violet "Golf Tint" lens improves contour recognition on the putting green, while the green "Outdoor Tint" (pictured) brightens shadows and increases contrast. Both lenses offer 100 percent UV protection.
