Hello dear, Bleach is a chlorine based chemical which is alkaline in nature. Chemical injury is considered a medical emergency. The eye tissues being very delicate may get seriously damaged due to its exposure. The pain, puffiness & redness may persist depending upon the amount & potency of the bleaching agent. So, it will be better to consult an Ophthalmologist & get a proper examination done. Based upon that appropriate management steps could be taken. Kindly let me know if you have any further queries.
