You need to remove them at the end of every day, clean and then store them in a contact lens case with solution, ready for your next wear. You do this for up to one month.
Some wearers want to wear their contact lenses just for sport, going out or during the weekend. In that case daily disposable contact lenses could be an option. But if you want to wear your lenses every day, monthlies could be the modality for you.
Monthly contact lenses need to be cleaned after use. It only takes a few minutes, so it’s no great hassle.
