Final week, POC released some highlights of their new 2020 gear that will be on show at Eurobike later this month. Amongst them, the new Aspire Solar Switch sunglasses function an electrochromic LCD lens that quickly and automatically alterations tint based on the intensity of ambient light. POC claims that these sunglasses can substantially boost vision, along with security and functionality in altering climate, light circumstances or environments, such as descending via mountain tunnels.
The new Aspire’s Solar Switch lens offers a darker tint in sunnier circumstances and quickly becomes lighter in shadow or cloud circumstances. The Solar Switch alterations tints (amongst levels three-four) instantaneously and automatically making sure you by no means require to get rid of your hands from the bike or take your glasses off at speed.
Usually to modify tint, sunglasses function photochromic lenses. Photochromic lenses function with molecules that darken when activated by the sun’s UV rays. This sort of lens commonly alterations tints at a slower price than an electrochromic style, producing them much less than best for circumstances exactly where a speedy modify is essential (like heading into a tunnel). By comparison, electrochromic lenses rely on organic supplies captured amongst two sheets of glass that alterations transparency in response to a modest electric current–the electric nature tends to make it extra instantaneous.
Other electrochromic sunglasses and goggles, like Spy’s 1 lens, rely on a rechargeable battery and energy switch to set off the electric present required to modify tint. Uniquely, the Aspire Solar Switch has been created to be powered only by the sun’s solar energy, needing no battery or charging so it will often be there, sustainable, and trustworthy.
I appear forward to seeing these in individual more than in Friedrichshafen in a handful of weeks time.
