his eyes are getting real bad again. he seems to have conjunctivitis every other week and his eyes are all red, gooey, and very sensitive to light (he has to wear sunglasses indoors, and cannot bear to look at a computer monitor). He lost the dosage information, but remembers that he needed to put them in 4 times/day. Could you tell me how many days he should do this for? If this is an antibiotic, there should be a standard amount of days this should be used, right? Please advise. Thanks!
