Hycosan Fresh Hycosan Fresh is a preservative free, lubricating eye drop for irritated or mild dry eyes. It contains sodium hyaluronate, a natural lubricant found in our eyes that has transformed the development of dry eye drops, & euphrasia (commonly known as eyebright), used for its soothing properties. Hycosan Fresh uses the unique, patented COMOD system to deliver a preservative free eye drop that is sterile for 6 months after first opening. This also ensures that just a single calibrated drop is dispensed per click to ensure accurate dosing & less wastage. Hycosan Fresh is safe to use with all types of contact lenses & you do not need to remove your lenses before applying the drops.
