Artelac Complete Eye Drops are preservative-free lubricating drops that come in 30 single-dose units. These drops provide long-lasting moisture and relief for dry, irritated eyes through their advanced formula containing hyaluronic acid. The single-dose units (SDU) ensure sterile application and are ideal for contact lens wearers since they are preservative-free. Each unit is for single use only and should be discarded after opening. The drops can be used as needed throughout the day to provide soothing relief from dry eye symptoms. Store at room temperature and keep out of reach of children. Do not use if the solution appears cloudy or if the single-dose container is damaged.
