This is a lens whose density changes depending on the amount of ultraviolet rays. Light colored lenses are used indoors, and sunglasses are used outdoors, and the lens color changes depending on the brightness. No color change will occur if there is no UV rays or the amount of UV rays is low, such as indoors, on cloudy days, in winter, or in the morning. ●What is blue light? Blue light emitted from LCD screens such as computers and smartphones is one of the causes of eye strain. It has the shortest wavelength and the highest energy among visible light, causing eye strain and mental fatigue. Furthermore, since sunlight contains light with similar wavelengths, it is thought that prolonged exposure to sunlight at night or before going to bed can disrupt the rhythm of the biological clock and cause sleep disorders.
