H2O lenses are the lens of choice for any patient who is looking for end of day comfort, clarity, and dry eye relief. We understand this is what matters most to patients, and when we make our lenses, we keep this in mind. Our lenses are made with advanced, breakthrough materials called hioxifilcon A and hioxifilcon D. These patented materials are made with a glycerin derivative, and have unique water binding properties allowing them to retain virtually all water content through the entire wearing period. The lens comfort, movement, and fit that patients experience when they first put them on, will be present throughout the whole day. H2O lenses are a great upgrade for patients who may still be wearing traditional disposable lenses, or have failed in silicone hydrogels.
