They change to color lenses when exposed to UV light outdoors, and return to clear lenses in places where UV light is not present, such as indoors. The density changes automatically depending on the "amount of UV light" and "temperature". The more UV light, and the lower the temperature, the darker the color becomes, and it becomes darker in the clear winter than in the summer.
