Contact lenses made of silicone hydrogel materials can often be used extensively, for longer periods of time. Biofinity Toric contact lenses are a great example of such contacts - they are made of comfilcon A, a patented CooperVision material that contains 48% water and is highly breathable. Thanks to these features, they keep your eyes fresh and healthy throughout the whole time they stay in your eyes. So now, even if you have astigmatism, you can wear your prescription contact lenses also at night, during sleep. Biofinity Toric contacts make sure that your eyes get enough oxygen and moisture even when your eyes are closed. Thanks to special Aquaform technology incorporated in the manufacturing process, these lenses never dry out and keep your eyes safe and sound.
