What are disposable lenses, frequent and planned replacement lenses?

Disposable contact lenses and frequent replacement contact lenses are designed to be worn for a specific period of time, thrown out and replaced with a fresh pair of lenses. “Disposable” refers specifically to lenses that are replaced every two weeks or less depending on the wear schedule prescribed by your optometrist or doctor. Disposable lenses are usually prescribed in multi-packs, providing several weeks supply at a time. “Frequent & planned” replacement lenses are lenses that are replaced on a planned schedule, most often either every two weeks, monthly or quarterly.

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 risk of serious eye infection even without any subjective deterioration in comfort. “Disposable Lenses” and “Frequent & Planned” lenses should be discarded after the recommended replacement time even if they are still comfortable thereafter.

Your eye care practitioner will determine the lens replacement frequency that is most appropriate for you. Lenses should not be worn for longer than the recommended wearing period.
