Update: January 20, 2026
Contact lenses expire on the date printed on the box and blister pack, and you should not wear them after that date. The expiration date applies to unopened, factory-sealed lenses stored properly, because sterility and packaging integrity can’t be guaranteed indefinitely. Once a lens is opened and worn, you should follow the replacement schedule for that lens type (daily, bi-weekly, or monthly) rather than the printed expiration date.
What to Check:
- Unopened lenses: check the “EXP” or expiration date on the carton and individual blister packs before use.
- Opened lenses: follow the prescribed wear and replacement schedule (for example, replace “monthly” lenses after about 30 days from opening, even if worn fewer times).
- Packaging condition: do not use lenses from blister packs that are torn, leaking, unsealed, or look contaminated.
- Storage: keep lenses in a cool, dry place and avoid extreme heat or freezing, which can damage packaging or solution.
- Stop wearing lenses and seek prompt eye care if you have pain, increasing redness, light sensitivity, discharge, or sudden blurry vision.
Contact lens expiration is based on sealed packaging and sterility, so always check printed dates and discard any lens that is expired or has damaged packaging.
