Biofinity XR (3 lenses)

Biofinity XR Contact Lenses

Biofinity XR are silicone hydrogel monthly lenses produced by CooperVision with the possibility of continuous wear, meaning when the lens is left in the eye during sleep. They are intended to correct high myopia and hyperopia, so they are produced with high plus and minus diopters.

Water content and oxygen permeability

The lens material Comfilcon A combines high water content together with good oxygen permeability. Biofinity XR brings balance between the ratio of the water content and oxygen permeability.

High permeability

Silicone is one of the hydrophobic (water-repellent) substances. The basic rule of hydrogel lenses is the more water the lens contains, the more oxygen permeates through. In the case of silicone hydrogel materials, the transmission of oxygen and metabolites takes place on the basis of their free passage through microscopic channels in the lens.

Technology AQUAFORM

AQUAFORM Comfort Science ™ technology uses a new silicone monomer, which provides more effective oxygen transmission through the lens. New technologies managed to link the hydrophilic (water-binding) and silicone (water repellent) components in a way that created a naturally moist material. The water content is equally balanced throughout the entire volume of the contact lens.

Biofinity lenses XR wear

Biofinity contact lenses XR are designed for daily use. They also allow occasional sleepover or continuous wear. However, this method of use should be approved by an ophthalmologist.

Biofinity XR anti-deposits resistance

The material of the contact lenses contains no ions (electrically charged particles) so the lenses are resistant to the accumulation of protein and lipid deposits that are a common output of tears and the external environment.

Comfortable to wear

Their aspheric front surface improves the optical properties of the lens and improves visual acuity in low light conditions and allows correction of lower astigmatism and presbyopia. The lens has a rounded edge to increase comfort and prevent eye irritation. The design of the rear surface of the lens is constructed by using several curves. Thanks to this, the pressure made by the lens is equally distributed over the whole surface of the eye.
