Biofinity Toric - Parameters and Specs

Biofinity Toric is a silicone hydrogel based contact lens developed by CooperVision. Introduced in March 2009, it features Aquaform Technology and a proprietary Optimized Toric Lens Geometry which provides a constant horizontal thickness across the ballast area for better lens stability and reduced rotation. Biofinity Toric contact lenses are made of Comfilcon A with 48% water and an oxygen transmissibility value of 116 Dk/t.

Highlights and Features

• High oxygen transmissibility for healthier eyes
• Soft and moist lens material minimizes deposits and provides excellent all-day comfort
• Round lens edge for more comfort
• Optimized ballast design for improved alignment with your eye
