Clinitas Soothe® has a uniquely high concentration of sodium hyaluronate (0.4% NaHA), which occurs naturally in the eye and hydrates the tear film. This helps provide long-lasting comfort protection. It can help provide relief from dry, tired eyes, computer eye strain, pollution, air-conditioning and much more. Once opened, the cap can be inverted to re-seal the dropper for use throughout the day for up to 12 hours. Each dropper contains up to 12 drops and comes in packs of 20 reusable vials, making Clinitas Soothe® economical and convenient for on-the-go use.
