The eyewash bottle contains an Isotonic sodium chloride solution with borate buffer and is for rinsing dirt and harmful substances in the eye. By placing the eye bath against the eye, the eye is kept open and the solution can be administered without waste or mess. The Cederroth eye rinse bottle has a shelf life of about 4 years and is a single use bottle, as once opened the eye rinse bottle is no longer sterile and there is a risk of contamination. Only use the solution if it is clear and the bottle is intact. For external use. Do not use on children under 3 years of age.
