Biomedics Contact Lenses are designed to effectively control the average spherical aberration in the lens and human eye. Spherical aberration is the inability of a lens to focus light on a common point. These contact lenses are able to focus light, providing you with clearer, crisper, sharper vision—regardless of the amount of correction required. At the same time, a rounded edge design provides excellent comfort. Ask your eye care professional about Biomedics 55 premier, or Biomedics Toric if you suffer from Astigmatism. And if you want your contacts lenses to last longer, consider Biomedics XC which utilize PC Technology™ to create a material that contains molecules of phosphorylcholine (PC), a substance found naturally in human cell membranes. The PC molecules attract and surround themselves with water, keeping these two-week lenses moist and comfortable all day long. Here at Eyecare Universe we are proud to offer you the best contact lens selection in the universe.
