Contact lenses expire, on average, 4 to 5 years after their manufacturing date, provided they remain sealed in their original packaging. Once opened, the lifespan depends on the type. Daily disposables should be thrown away after one use, bi-weekly lenses last up to 2 weeks, and monthly lenses can be used for up to a month. Always check the packaging for the specific expiry date and discard any contacts past their recommended usage period to avoid eye infections or discomfort.
FAQs & Answers
- How can I tell if my contact lenses have expired? Check the packaging for the printed expiration date. Do not use contacts past this date even if unopened, as expired lenses can be unsafe.
- What happens if I use contact lenses beyond their recommended usage period? Wearing contact lenses past their intended use increases the risk of eye infections, irritation, and discomfort.
- Can daily disposable lenses be reused if they feel comfortable? No, daily disposable lenses are designed for single use only and should be discarded after wearing to prevent eye health issues.
- Are contact lenses safe to use after opening if stored properly? Yes, but only within their recommended wearing period (e.g., two weeks for bi-weekly lenses) and if stored properly in clean solution.
