Murine Contacts Refresh & Clean are daily moisturising eye drops for all types of contact lenses. Moisturising eye drops clean, lubricate and hydrate all types of contact lenses as you blink, with no need to remove them. Murine eye drops are more than just moisturising and lubricating eye drops because they also hydrate and clean all types of contact lenses while the lenses are worn. Due to their special formula and cleaning action, they are particularly recommended for users who wear their lenses over long periods of time or who have deposit build-up problems.
