You may not think much about the expiration date on your contact lens box, but it is there for a good reason. Packaged medical devices like contacts are assigned an expiration date after which the manufacturer can’t guarantee that the product will be free from contamination. A contact lenses expiration date is clearly labelled on each box, it may require some searching but this is a date you want to make note of. Contacts are in constant contact with your eyes and it’s especially important to make sure you don’t use lenses from a package that’s past its expiration date.
