Eyes blind because hit blow if not broken, can only, sometimes can be normalized but still there are defects or wounds on the eye, if I want I give eye drops medicine, cover with plaster and placed in dark place for 2 days - 4 days usually has returned, but never once until one week does not return alias remain blind (defective) forever. If you use a natural remedy can use young koro leaves then puree, the air is dripped on the eyes of the sick. good luck
