The Charlie V Twisting-Hinge Sunglasses aren’t just another pair of eyewear. These unique glasses have a hinge that pivots, making them take up less space. If you keep them in your pocket, you won’t deal with any annoying bulges. Furthermore, if you continue to use the protective case, it won’t be big and bulky one like traditional sunglasses cases. Other than the twisting hinge, these sunglasses fight glare. When you’re skiing the mountain, Charlie V glasses will help keep your eyes protected against the bright light reflecting off the snow. While they’re stylish black-frame sunglasses, they’re also durable enough to withstand your adventurous outdoor lifestyle. With six lens types to choose from, ranging from smoked black to gradient, you’ll find one that suits your style and needs best.
