Biofinity is a monthly disposable silicone hydrogel contact lens manufactured by CooperVision. Biofinity was created through the innovative use of a different type of silicone hydrogel architecture. The result is a naturally water-loving lens that stays moist and hydrated throughout the day. It is designed for daily-wear use.
Biofinity’s unique lens design optimizes the relationship between oxygen and water using the patented Aquaform technology. Oxygen and water are both crucial components of good eye health.
Aquaform technology establishes more exposed and accessible sites for water bonding, which enables moisture in the lens. Because the lens material is naturally wet, Biofinity lenses do not require nor contain any additives for coating, wetting, or surface treatment.
This technology is designed to create a material with longer silicone chains. Specialized molecular sites located on these chains allow hydrogen bonds to form with water molecules and create a water-loving lens material that retains water. The result for wearers is a lens that is highly resistant to dehydration and therefore more comfortable.
In general, higher silicone content signifies higher oxygen permeability, lower water content and a higher elasticity. Aquaform technology is able to combine high water content with a low elasticity (modulus) and high oxygen transmission. This increases comfort, eye health, and lens performance for the wearer.
Biofinity’s back-surface design evenly distributes the weight of the lens across the cornea, alleviating pressure and minimizing potential discomfort. This also reduces irritation to the cornea and conjunctival tissues. The front surface of the lens is aspheric, diminishing visual distortion. The overall design of the lens increases visual performance and allows for quicker, easier alignment and fitting.
Advances made to silicone hydrogel technology in recent years make it possible for most conventional hydrogel wearers to be fitted for silicone hydrogel lenses. Relative to other silicone hydrogel lenses, Biofinity excels in comfort, vision, and overall lens performance.
Biofinity contacts are available, with a valid prescription, at Contact Lens King.
