Contacts generally expire based on the date they were opened rather than the number of uses. For instance, daily disposable lenses should be thrown away after a single use, even if worn for only a few hours, while monthly contacts are good for 30 days after opening—not based on the number of times they've been worn. It's crucial to follow the usage guidelines provided by the manufacturer to avoid eye health issues.
