Special moisturizing Aqua formula included in Air Optix Aqua contact lenses provides the best hydration level that lasts throughout the whole day giving you a feeling of comfort and freshness. A combination of silicone and hydrogel greatly influences the way Air Optix Aqua feel on the eyes making it extremely comfortable and safe. The hydrating system and the composition of the lens assures that they are constantly moisturized and transparent as well as silky soft and smooth. Thanks to these features, Air Optix Aqua wearers can enjoy a great vision quality and healthy, bright eyes. Every lens user realizes that the comfort of lens usage depends greatly on the level of hydration it provides and how long it is being provided for. Thanks to the incorporation of a special hydrating system in Ciba Vision contact lenses (currently Alcon), they maintain both of those parameters on a high level, providing comfort as well as health and safety.
