As the wind whips your face like a pony swats its tail aggressively at flies, you're made incredibly aware of the fact that your shades not only don't fit, but they're pinching your nose like nobody's business, which that bitter cold breeze has made you more painfully aware of. Thankfully, the folks over at Bliz created the Force Photochromic Sunglasses for larger faced humans like you, so you no longer have to squeeze into frames that don't fit you. Also, the Force Photochromic Sunglasses are modeled after their smaller frame Rapid counterpart and come equipped with a durable hard case, cleaning cloth, and a convenient adjustable strap that's super stretchy and allows you to secure the glasses onto your head for a fine tuned, slip free fit. Additionally, the Forces come with a removable sweat brow that's terrific for preventing sweat from dripping into your eyes and consequently maintains optimal visibility while conducting your high intensity workouts. Utilizing the perfect curve lens technology, the Force Photochromic comes fully equipped with two polycarbonate lenses that provide UV protection from harmful UVA or UVB rays these options include one bright light and one universal ULS lens. Both lenses are crafted with a photochromic treatment which enables you to transition between lights and darks with ease while the anti scratch, oleophobic, hydrophobic, and anti fog coatings ensure that no water, scratches, stains, or fog will obstruct your view while running, cycling, or simply kicking butt. However, should you suddenly take a digger and your shades go flying, they're guaranteed to be shatterproof although we don't recommend doing this on the regular. Additionally, the Rapid ensures a customizable fit with its adjustable nose pad, rubber wire core, removable sweat bar, and adjustable stretchy strap.
