About ten years ago, silicone was added to soft contact lenses. This made the lenses highly breathable. The oxygen transmission went from an average of 28 units to about 120 units. This is obviously much healthier for human cornea. There are numerous lenses available in this format including: B&L PureVision 2, Cooper Biofinity, Acuvue Oasys, and Ciba Night and Day. Longmont Vision fits most patients with these new lenses, and we work to custom fit each patient with the best lens for comfort and vision.
