Photochromic glasses are great for things like heading out on evening bike rides, as their tint gradually lightens while the sun goes down. If you're bursting in and out of shadowy forests or zipping through dark tunnels, however, the slow reaction time of such glasses just can't keep up. That's where Uvex's Variotronic glasses come in, which use electrochromic tech to change tint in just a tenth of a second. I recently got to try a pair out, and there's nothing shady about them.
Well, that didn't take long. In less than a year, electrochromic sunglasses have gone from being experimental to an actual product, with Dutch startup Ctrl announcing its tint-on-demand Ctrl One
cycling glasses just this month. Should you prefer multi-use
electronically-tinting sunglasses, however, you might want to get
yourself a pair of Skugga shades.
Some hobbyists might already be familiar with micarta, a solid material
made from layers of denim that have been bonded together with resin.
While it's usually carved to create objects such as knife handles, UK
startup Mosevic is using a micarta-like substance to make something else – blue jeany-looking sunglasses.
