A 2016 release by Cooper Vision, Avaira Vitality improves upon its predecessors with Class 1 UV protection and overall increased comfort. Most popular lenses are made of silicone hydrogel, but Avaira Vitality utilizes the 3rd generation of this breathable material. It has the lowest silicone content of any two-week lens, allowing for 55% water content in the contact. Aspheric Optics Technology – Many lenses rely on a simple spherical design, but even when perfectly manufactured these can produce “spherical aberrations” by focusing light at different points. To save you from this blurred vision, Avaira Vitality utilizes an aspherical shape. By better adapting to your eye, aspheric optics makes vision clear and crisp. Avaira Vitality is a 2 weekly disposable lens. The lens quality allows it to last an entire week, assuming proper nightly care, without loss of safety or comfort. Weekly wear lenses strike a balance between daily and monthly wear. Avaira Vitality will be more cost effective than daily lenses that you dispose of nightly. You also don’t have to wait an entire month to switch to a fresh lens. The unwary consumer will pay over $35 for a box of six lenses. At Simple Contacts, we can do better. Not only does Simple Contacts offer competitive prices on all its lenses, but new customers can get a 20% discount. No hassle of mail-in rebates. Shipping is easy and free.
