How often should contact lenses typically be replaced?

Contact lenses should be replaced on a schedule that varies according to their type, which is why the correct answer emphasizes the importance of considering the specific lens used. There are different categories of contact lenses, including daily disposables, bi-weekly disposables, and monthly disposables.

Daily disposable lenses are designed for one-time use, meaning they should be discarded after a single day of wear. Bi-weekly lenses are intended to be worn for up to two weeks before replacement, while monthly lenses can generally be worn for 30 days before needing to be changed. This variability is crucial for maintaining eye health, as the replacement schedule helps to minimize the risk of infection and discomfort, ensuring that lenses remain effective and safe for daily wear.

Understanding the replacement frequency is essential for promoting proper lens care and hygiene, which ultimately contributes to the overall health of the wearer's eyes.
