The faster the lens changes color, the better, for example, from a dark room to a bright light outside, the faster the color changes, in order to prevent the damage of strong light/ultraviolet rays to the eyes in time

Generally speaking, film discoloration is faster than substrate discoloration. For example, the new film layer color change technology, photochromic factors using spiropyran compounds, which has better light responsiveness, using the molecular structure itself to reverse the opening and closing to achieve the effect of passing or blocking light, so the speed of color change is faster.
