The instructions on the label on the bottle or box should give you a good indication. For an answer more specific to you, you should consult a medical professional.
After all, there are two possible meanings to your question - how long does a dose last, and how long does the bottle last. But both answers could be derived from the label.
(Note: It the bottle lasts longer if there are no artificially created reasons for needing to use it more, such as the ingestion of delta-9 tetrahydrocannabinol.)
15-10 minutes. (to remove red eye)

Personally, I would say that ingesting Visine constitutesquestionable behavior.(Don't trick someone into ingesting Visine. It's not harmless, and could result in a coma or even death.)
