Question: how many eye drops are in 15 ml?
Answer: Did you guess correctly? A standard eyedropper dispenses 0.05 ml per drop, meaning there are 20 drops in 1 milliliter of medication. Let's do the math: a 5 ml bottle has 100 doses and a 10 ml bottle has 200 doses. (Most eyedrop prescriptions are dispensed in either 5 or 10ml bottles.)
