As technology advances, so do lenses. In the past, they were made exclusively of glass. Today, most are made of high-tech plastics. These new ones are lighter, don’t break as easily as glass, and can be treated with a filter to shield your eyes from damaging ultraviolet (UV) light. There are almost as many coatings as there are lenses. As experts in the field, we at Lawrence Optical Inc want to introduce you to our Nikon Pure Blue and Nikon SeeCoat Next Blue lens wear. We have written down information on both types of lenses so that you are better equipped to choose between the two.
