When the canister lens is irradiated with visible and short-wave ultraviolet light in sunlight, the color will be darker and the light transmittance will be reduced. Inside or in dark places, the light transmittance of the lenses increases and the color disappears. The optical properties of the lenses are automatic and reversible. Photochromic glasses can adjust light transmission by changing the color of the lenses.
