Color changing lens is made of optical glass containing silver halide microcrystal. According to the principle of reversible reaction of light color tautometry, it can quickly darken under sunlight and ultraviolet radiation, completely absorb ultraviolet light, and show neutral absorption to visible light. Back to the dark, can quickly restore colorless transparent.
The electromagnetic rays just beyond the red end of the visible light spectrum are called infrared - they are warming, but invisible. (The "warming lamps" you see keeping food warm at your local eatery emit infrared radiation. But these lamps also emit visible red light so people know they are on! The same is true for other types of heat lamps.)
On the other end of the visible light spectrum, blue light rays with the shortest wavelengths (and highest energy) are sometimes called blue-violet or violet light. This is why the invisible electromagnetic rays just beyond the visible light spectrum are called ultraviolet (UV) radiation.
