hydraSense® Eye Drops are preservative-free
Many multi-dose eye drops contain preservatives to stop bacteria and fungus from growing and multiplying inside the bottle. Preservative-free eye drops use different delivery systems to prevent bacteria or fungus from growing inside them. For some brands, that means single-dose dispensers that you throw away after each use.
The new hydraSense® Eye Drops use an innovative in-bottle filter that allows them to be both multi-dose and preservative-free. Canadian optometry guidelines favour the use of preservative-free eye drops, if you’re using the product more than four times a day.1
