The smoke is made up of many small particles which means it is a kind of foreign objects, and when the smoke gets into the eyes, it will get in touch with the cornea and the eyeballs. As we all know, human eyes are very sensitive and vulnerable to foreign objects, so the cornea and eyeballs can easily be rubbed and ground by the small particles, thus causing some blood streaks in the eyes and making the eyes feel very painful. You should use clean flowing water to wash your eyes clean, and then apply some physiological saline or antibiotic eye drops into your eyes, and have a rest. After doing these, if your eyes still hurt very much, then it may be that the smoke is poisonous and you should go to the doctor's as soon as possible to take correspondent treatments.
