I wear monthly disposable contact lenses but only on an infrequent basis, once or twice a week. My optometrist told me I still need to discard the lenses one month after opening even if I have only worn them five times. Why?
Disposable contact lenses are licensed and given approval for a specified duration of use .This commences when they are removed from their sterile packaging. It means that after this advised time, be it two weeks or one month etc, the performance of the lens cannot be guaranteed by the manufacturer. After this specified time the lens may be less resistant to deposits and be more fragile and the visual performance and lens integrity cannot be compromised.
It is not your optometrist who dictates when the lenses need to be discarded but the licensing authority for contact lens manufacturers.
