Treat yourself to superior comfort and vision with up to 6 nights/7 days of continuous wear. Biofinity contact lenses use Biofinity Aquaform Comfort Science technology to bring contact lens wearers an advanced level of comfort in a monthly disposable lens. By bringing together two essential elements, high oxygen performance and a naturally wet lens material, your eyes will stay healthy and the lenses will stay soft and deposit-resistant with the water-retaining lens material. This, combined with a lens design that focuses light better for higher resolution and deeper focus, make for a truly remarkable silicone hydrogel lens. 6 lenses per box.
