The invention discloses glasses for warning about eye fatigue. The glasses comprise a glasses frame, lenses and glasses legs. The glasses further comprise a radiation induction device, a control device, a timing device, a warning device and a resetting button. The output end of the radiation induction device is connected with the control device. The output end of the control device is connected with the timing device. The output end of the timing device is connected with the warning device. An output device of the warning device is connected with the resetting button. The other end of the resetting button is connected with the timing device. The radiation induction device is an electromagnetic radiation induction device. An infrared flickering device is adopted as the warning device. According to the glasses, the radiation intensity of the glasses portion of people can be obtained, and therefore the safe eye using time of people is obtained, and people can be effectively reminded of eye using rest time in time. The eye fatigue problem caused due to the fact that people are too concentrated to forget time is solved.
