Coopervision Biomedics 55 Premier™ contact lenses were found in a recent clinical study to be the only lens which effectively controlled spherical aberration or the inability of a lens to direct light on a common point. Biomedics® 55 Premier™ controls aberration resulting in clearer, crisper, sharper vision. A new thinner patented edge design provides unsurpassed wearing comfort compared to other contact lenses. Biomedics 55 Premier™ is the clear choice, a superior performing aspheric lens. Two week daily/one week extended wear as directed by your physician. Sold as 6 identical lenses per box.
