Available exclusively from Hammacher Schlemmer, these are the glasses that help golfers locate golf balls obscured by shadows and thick rough. The lenses have a blue pigment that filters light as it passes through, making white golf balls easier to locate against dark backgrounds. The glasses have a flexible plastic-resin frame that wraps around the face for optimal comfort and fit. Includes a drawstring bag that stores and protects the glasses. Not intended for use as sunglasses. One size fits most. 1 3/4" H x 5 3/4" W x 6" L. (1 oz.)
