Low-temperature photochromic lens components and ski goggles

Abstract

This invention provides a low-temperature rapidly photochromic lens assembly, comprising an outer protective layer, a heat insulation layer, and a photochromic layer. The outer protective layer, the heat insulation layer, and the photochromic layer are arranged sequentially from the outside to the inside. The heat insulation layer has a heat insulation function, thereby isolating the photochromic layer from the cold external environment, allowing the photochromic layer to escape the low-temperature environment. Furthermore, when ski goggles are worn on a person's face, the heat from the person's face can be transferred to the photochromic layer located inside the heat insulation layer, thereby further increasing the temperature of the photochromic layer. This greatly improves the problem of the photochromic layer's transmittance responding to changes in light intensity at low temperatures.
