When to Change Your Contact Lenses

Simple Contacts

Slept in your contacts again? Can’t remember when you started a new set? It happens, but continuously wearing your contacts too long puts your eyes at serious risk. Overwear can lead to discomfort, torn lenses, irritation, and—worst case—an infection. How often you change your contacts depends on the type you wear, but it’s incredibly important to adhere to the guidelines, so we’ve shared them below.

Daily disposable
These contacts are only meant to be worn for a single day. When wearing dailies, there’s no need to ever put these contact lenses into a case or use cleaning solution. When they come out of your eye, they should go straight into the trash.

Weekly disposable
These contacts have a longer wear period of one to two weeks, depending on the brand. They should be removed and stored in a case with fresh solution each night, then disposed of after no more than two weeks of wear.

Monthly disposable
These contacts have an even longer wear period of one month. They should be removed and stored in a case with fresh solution each night, then disposed of after four weeks.

Traditional disposable
Although much less common, you can also be prescribed traditional lenses that are good for anywhere from six months to year. Follow your eye doctor’s recommendation for how often to open a fresh pair.

Regardless of which type of contact you’ve been prescribed, it’s important to remember that the prescribed wear schedules are for a maximum amount of time. You may find that a contact lens starts to irritate your eye or gets torn before you’ve worn it for the full period. If this happens, throw it out and open up a new lens. In the case of contacts, less time is more, so remember to always put your eyes first.

Tips for upkeep

  • Always wash your hands before handling your lenses.
  • When you put your contacts in, empty out the old solution and let the case air dry. Don’t reuse old solution.
  • Make sure you remove your contacts nightly. Do not sleep in your contacts unless you’ve been prescribed to do so by your doctor.
  • Rinse your contact lenses with fresh contact solution before storing them in your lens case.
  • Replace your lens case every three months or so.
