Disposable lenses are supposed to be discarded after a prescribed time. Can I continue to wear my lenses if they are still comfortable after the recommended wearing period?
A. Lenses should not be worn for longer than the recommended wearing period. The purpose of replacing contact lenses on a frequent basis is to prevent discomfort, dryness, blurred vision and allergic reactions that can result from a build-up of protein and lipid deposits on the lenses. As the deposits age and chemically change on the lens, they contribute to these irritations. The changes in the chemical composition of the deposits also increase the probability that bacteria may adhere to a contact lens, increasing the health risk even without any subjective deterioration in comfort. Check with your eye care practitioner for the lenses and lens replacement frequency that are most appropriate for you.
