Product Description Refine One Step Solution is a preservative free peroxide solution for contact lens wearers. This lubricating contact lens solution effectively cleans your lenses whilst leaving your eyes and lenses deeply hydrated. This peroxide solution is suitable for all lens types, including rigid gas permeable, soft and silicone hydrogel contact lenses. This solution is especially well suited to those with allergies or sensitive eyes, as it doesn t contain any preservatives. This 3% hydrogen peroxide solution must be neutralised before coming into contact with the eye. Ensure the solution has soaked with the built in neutraliser for at least 6 hours. You should also never rinse your lenses with Refine One Step solution before inserting as this can cause burning and irritation. This 250ml size is enough solution to last contact lens wearers a month. You can also stock up and save with Refine One Step Solution 250ml Triple Pack. Need more optical advice help?
