More or less 2.5ml of eyedrops, with the usage details you are giving, should last you 15 days.

Sandoz claims that in the 2.5 ml bottle, there are 80 drops which is nearly 3 months. At one drop a day, the solution should last 80 days NOT 15 days.

1ml=16drops so 2.5ml is about 37 drops so a 2.5ml will only last about 2 weeks and 3 days.

You should check the Sandoz pdf drug description that claims the 80 drops per 2.5 ml bottle.

There are 20 drops per milliliter. If you have the 2.5ml bottle, that's 50 drops. If you're only using 2 drops per day, it will be a 25 day supply. I'm a CPhT, so I know what I'm talking about.

I think it's 2.5 ml in total solution 4 ml, thus 80 drops.

Oops, it's 4ml bottle, 2.5 solution. Literature does say 80 drops though, so worth checking with manufacturer.
