Bleach consists of sodium hypochlorite, hydrogen peroxide and other chemical substance. All these substance are oxydic. When bleach comes into people's eye, it will react there and oxidizing reaction will release heat so that you will feel burning in your eyes. You should rinse your eyes will code clean water immediately. Oxide will be less sensitive at lower temperature and the running water will take away the heats, so that the burning will be partly relieved. And then, use antibiotic eye-drops as it is helpful to stop oxidizing reaction. At last, put on the ointment to help the eyes recover. If it doesn't work even you have done all these job, you have to go to see a doctor.
