The Julbo Truck polarized photochromic sunglasses grant you the extra mile in your travels, offering impeccable optical clarity that adjusts to rapidly changing conditions. Falcon(R) polarized photochromic NXT lenses respond quickly to changing light conditions, darkening in bright light and lightening in dim light. Falcon lenses are multipurpose and recommended for driving; lenses are sensitive to visible light and will darken behind a windshield. Polarized lenses reduce 99% of visible glare from water, snow, sand and pavement for increased visual acuity and decreased eye strain. NXT polyurethane lens material provides exceptional optical clarity and visual comfort. Extremely flexible and impact resistant, NXT lenses are guaranteed not to break or crack. Brown lens tint cuts down on overall brightness without distorting colors. Anti-reflective coating reduces eye strain; oil-repellent coating prevents grease marks from fingers, hair and sunscreen. Durable, lightweight metal frames feature flexible temples that adjust easily to your face shape. Julbo Truck sunglasses include a protective case.
