Product details
Biofinity XR (Comfilcon A XR) monthly contact lenses from CooperVision are made using the same materials and technologies as standard Biofinity monthly lens but meet the demands of patients with higher prescriptions.
These advanced silicone hydrogel lenses can be comfortably worn all day, thanks to the ultra-breathable Aquaform® Technology. In fact, in most cases you can continuously wear a pair of Biofinity XR lenses for up to six nights and seven days. It's best to check with your optician first though, as everyone's eyes are different.
Biofinity XR contacts are available in a range of longsighted powers from +8.50 to 15.00, and short-sighted powers from -12.50 to -20.00.

| 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. | 160 |
