It’s best to follow the manufacturer’s replacement schedule and not wear your contact lenses for longer than recommended. However, if you are finding your contacts cause eye irritation or making your dry eye symptoms worse, it’s worth considering swapping them out for new lenses more often. “If you have dry eyes and can wear contacts comfortably, there is no reason to change them more frequently than is recommended by the manufacturer,” says Dr. Shedlo. “If the contacts are not very comfortable, you may want to consider reducing the wearing time and remove your lenses.” Many of the contact lenses on this list are not recommended for overnight use either, so make sure that you are removing them regularly and not wearing them longer than recommended.
