Disposable contact lenses are an easy and convenient choice for many people. Because they are intended to be used for only a short while, wearers need to follow a contact lens replacement cycle, of which there are many options.

Different manufacturers have different options for how often their lenses need to be replaced. Some brands offer daily contact lenses, which are literally worn one day and then thrown away. Others are designed to be replaced every seven to 30 days, depending on the specifics.

Regardless of the choice of duration, the FDA recommends users to allow their eyes at least one night without using contacts at all to so that the eye can rest naturally.

It is important and healthy to follow a fixed contact lens replacement cycle. As time passes, lenses become hazy as proteins in tears remain on the lenses. Dust, pollen, and other irritants accumulate as well. Sticking to a contact lens replacement cycle keeps the freshest lens possible near the eye, which promotes good eye health and keeps eyes looking bright.

Initially, worrying about contact lens replacement seems like a reason to reject wearing disposable contact lenses. However, disposable lenses offer the convenience of wearing them overnight, along with the ease of never having to clean them. The FDA does note that that if disposables are removed, they should be cleaned and disinfected before reinserting into the eye to prevent infection.

Sticking to a replacement schedule is easy, as there are numerous websites that offer a variety of contact lenses at affordable prices with convenient shipping directly to the wearer’s home. The FDA and FTC both recommend only buying from reputable suppliers who should ask for a valid prescription. Depending on the state, contact lens prescriptions need to be updated once every one or two years.
