Rivbos Multifunction Sports Sunglasses are the ideal companion for various outdoor activities. Whether you're into sailing, cycling, running, or just the casual stroll in the park, you'll surely find a Rivbos lens to match your vision needs! The Dark Polarized lenses filter out unncessary glare from reflected surfaces, protecting your eyes from too much light that can cause damage to the retina. Hiking in the early morning with mist still clinging around the hiking trail? Snap on the Light Blue lens to enhance optic resolution and become safer in your walks. Cloudy weather bringing you down? Use the Rivbos transparent colourful optic lens. Cycling or driving on a very sunny day? Try the colourful optics lens which absorbs ultraviolet and infrared rays for better vision. Travelling at night? Go for the yellow lens to enhance light intensity for better visibility.
