The invention discloses a kind of intelligent protective glasses, comprising a frame, mirror legs and photochromic lenses; a controller and a defogging device are arranged in the frame, and the controller is connected to the defogging device; batteries are arranged on the mirror legs, and the batteries are respectively It is connected with the controller and defogging device; the photochromic lens includes a transparent anti-reflection layer, an ultraviolet absorbing layer, a transparent lens, a light absorbing layer, and a photochromic layer in turn; the photochromic layer includes 50% to 75% of polypropylene, 3% ~8% propylene glycol butyl ether, 0.1%~0.3% 1,2-bis[2-methyl-5-(3,4-difluorophenyl)thiophen-3-yl]perfluorocyclopentene, 0.1 ~0.2% WO 3 , 0.3% ~ 0.5% TiO 2 , 0.1% to 0.2% naphthopyran, and the balance is polyethylene. The photochromic lens of the present invention can not only realize photochromic change, but also can absorb ultraviolet rays and other harmful light rays, and can also automatically change color according to light intensity, effectively avoiding damage to eyes caused by long-term use of computer and mobile phones.
