App-controlled smart sunglasses change tint on demand

Tech start-up, Ampere, wants to help you protect your eyes with Dusk, the “world’s first smart sunglasses”. Unlike classic transitional glasses made with photochromic lenses that automatically switch tint in response to brighter light, Dusk’s are made with electrochromic lenses that change tint in response to electrical signals. The lenses block 100% of UVA/UVB rays, and the frames weigh just 26 grams. A button on the underside of one arm cycles through three preset tint levels; for more detailed control the Ampere app has a sliding bar that lets users pick from zero to 100 per cent tint; the tint switch happens in 0.1 seconds. Favourite settings can be saved to find later. Dusk also has speakers and a mic for hands-free phone calls, summoning Siri and Google Assistant or listening to music, audiobooks and podcasts. The speakers are “open ear”, but only the wearer will be able to hear them. Use the Ampere app to sound an alarm to help you find them; there’s also space for Apple’s Air Tag in Dusk’s charging case, so that you never misplace it. Dusk’s IP65 rating means they can withstand dust, rain and other elements. The Dusk comes with 7 days of use when running just the tint-control features.
