[PConline News] At present, more eye-shielding dual-purpose glasses use transitional lenses. These glasses are theoretically a good idea, but they actually have some obvious disadvantages. Because of this, researchers from the Georgia Institute of Technology are developing an alternative product - transparent glasses that can be manually colored by the user as sunglasses. Transition lenses include a silver halide molecule that temporarily changes color when exposed to ultraviolet light. This will cause the lens to darken, and then part of the light will be easily blocked. However, one of their problems is that the process of changing from transparency to coloring often takes several minutes. If you are doing activities such as driving or even flying a plane, this is obviously not fast enough. In addition, if you are in a dark environment like the car, looking at the bright areas, they will not be colored. In this way, it is easy to accidentally injure the eyes. If it is serious, it will also cause traffic accidents. This is not a joke. In contrast, glasses developed by the Georgia Institute of Technology can be colored and faded anytime, anywhere. Simply dial the power switch. Those lenses contain electrochromic polymers that change color when they encounter current rather than ultraviolet light. In prototype glasses, blue-green, yellow, orange, and blue polymers are mixed to create a brown coloration that blocks up to 70% of light in just a few seconds. However, other colors can also be formed by changing the ratio of polymer color. According to the research team led by Anna Österholm, the inkjet printing/blade coating technology used to manufacture lenses can be easily used to expand commercial production. In fact, New Jersey-based startup Ashwin-Ushas is developing its own electrochromic sunglasses that use photodetectors to automatically adjust the degree of coloration. The relevant research papers of the Georgia Institute of Technology were recently published in the Journal of Applied Materials and Interfaces of the American Chemical Society. Looks really good, look forward to its release. Wear digital channels online! Home click to enter
