Photochromic spectacles which use solar energy as the power source include a frame, two lenses arranged in the frame, and a driving circuit. Each lens includes a substrate, an electrochromic film and a solar cell film. The solar cell is a transparent and outer film and absorbs infrared light and ultraviolet light from the sun, to convert the infrared and ultraviolet light to electrical power. The driving circuit is arranged on the frame and electrically connected with the electrochromic film and the solar cell, the driving circuit can be switched to apply or not to apply electrical power generated by the solar cell film to the electrochromic film to darken the spectacles. |
