The mercury reflective film is applied to the outer surface of the lens (actually a semi-transverse semi-permeable membrane), which greatly reduces the intensity of light (including ultraviolet rays) entering the human eye and protects the eyes. 4, more in line with the trend, increase the aesthetic appearance of sunglasses. 5. Note that the mercury sheet will have different color changes under the refracting of different angles of light, not the color difference.
