Dusk Sport are patent-pending sports sunglasses with electrochromic lenses, which lets athletes adjust the tint of their lenses to their exact desired level. The tint can be manually adjusted on the frame or on the app. For a hands-off approach, users can activate InstaOptic™, a new tint-changing technology that leverages an ambient light sensor to automatically adjust the tint. Dusk Sport have premium open-ear speakers and microphones built into the arms, as well as noise canceling technology. The Ampere app unlocks additional features like Huddle Mode™, which allows athletes to communicate with each other through the frames.
