Product details
Purevision Multifocal contact lenses offer a welcome change for those wearing bifocal or varifocal glasses. Providing much more freedom than glasses, these clear and comfortable lenses are perfect for those wishing to try out lenses for the first time.
PureVision Multifocal silicone hydrogel contacts are made with AerGel technology, which assists in keeping the surface of the lens free from protein build-up and other types of debris. This also allows for a substantial degree of oxygen to properly reach the eye, helping to maintain optimal health.
If you have avoided contact lenses in the past due to dry eyes, you may be pleasantly surpised by just how comfortable Purevision Multifocal can be. The Silicone Hydrogel balafilcon material ensures the lenses remain hydrated throughout the day, locking in moisture for added comfort.
Designed for extended wear, PureVision Multifocal lenses can provide up to 30 days of continuous use. That means you won’t have to take the time to remove, cleanse and care for them every night, offering you a much greater level of convenience than your average lens. However, continuous wear isn’t for everyone, so we recommend you talk to your optician before wearing for more than a day.

| Oxygen permeability (Dk/t) It indicates the amount of oxygen which passes through the lens. The oxygen permeability is an key indicator of the lens material. It determines how much oxygen (which is necessary for proper performance) receives a cornea of our eyes. The higher the value, the better. Dk/t is common used and it states: the Dk per thickness of the lens. Usually for a lens at -3.00D, which makes it easier to compare different lenses brands. Ranges from 10-20 Dk/t to over 170 Dk/t. | 130 |
