Preference® Toric contact lenses are durable, easy to handle and virtually maintenance free. Meeting the needs of those with astigmatism, these soft contact lenses are an excellent alternative or addition to bifocal glasses or readers. The unique lens design of Preference Toric® contact lenses is ideal for active lifestyles. While tetrafilcon A produces a more durable lens, this deposit-resistant material also promotes greater comfort and healthier eyes. And because it resists protein and other debris produced from tears, you'll be less likely to develop eye irritations or end-of-day dryness.
