Clinitas Soothe is a gentle preservative-free eye drop which contains the highest concentration of sodium hyaluronate (0.40%) available in an eye drop. Sodium hyaluronate (or hyaluronic acid) is a naturally occurring product in the eye and widely used in many eye drops for its fast and effective relief of dry eye symptoms. Clinitas Soothe is available as either a 10ml multi-dose bottle (which can be used for up to 90 days after opening) or a box of 20 resealable vials (about 10 drops for use over a day). Both forms of the product are completely preservative free and ideal for: Contact lens wearers, dry or sore eyes caused by working at a computer, reading and other close work. Watching TV, driving and other activities using concentration (i.e. reduces blink rate). Modern living - air conditioning, heating, air travel and pollution. Tired eyes. Dry eyes following laser surgery. Dry eye sufferers with sensitivity to preservatives. Dry or sore eyes associated with the menopause. Clinitas Soothe can be used in conjunction with Clinitas Hydrate at night.
