Engineered for performance and precision, the Boll Lightshifter XL sunglasses are a must-have accessory for superior comfort. Featuring a semi-rimless shield silhouette, this design has been refined as a slightly larger rendition of the best-selling Lightshifter, offering extra coverage. Boll’s cutting-edge Phantom clear and lava photochromic lenses deliver adaptive protection from UV rays while delivering unclarity.
