For natural moisturising Hylo-Vision SafeDrop Gel is a sterile wetting agent in the innovative SafeDrop bottle, a preservative-free multi-dose container co-developed by OmniVision. It is used to improve moistening of the surface of the eye and is suitable for moistening all types of contact lenses. Hylo-Vision SafeDrop Gel contains 0.3% hyaluronic acid, a natural substance that is also present in the structures of the human eye and in the tear film. It protects and moistens the surface of the eye and makes it slippery. This provides long-lasting relief from the symptoms of dryness, irritation and mild irritation, particularly in the case of environmental stress, e.g. from air conditioning, wind, cold, dryness or air pollution or in the case of tiredness and visual stress caused by intensive viewing, e.g. from computer screens, microscopes or long car journeys or in the case of mechanical stress, e.g. B. by wearing hard or soft contact lenses or through diagnostic procedures on the eye.
