III. Features

1. PC Polycarbonate Lens

Semi Finish 1.59 Index Lenses , 70MM Dia Round Top Polycarbonate 1.59 Lenses Blanks

Polycarbonate lenses. In the early 1970s, Gentex Corporation introduced the first polycarbonate lenses for safety glasses. Later that decade and in the 1980s, polycarbonate lenses became increasing popular and remain so today.

Originally developed for helmet visors for the Air Force, for "bulletproof glass" for banks and other safety applications, polycarbonate is lighter and significantly more impact-resistant than CR-39 plastic, making it a preferred material for children's eyewear, safety glasses and sports eyewear. Best of all, polycarbonate lenses are virtually unbreakable, making them a great choice for children and active adults.

2. Round Top Bifocal Lens

Semi Finish 1.59 Index Lenses , 70MM Dia Round Top Polycarbonate 1.59 Lenses Blanks Bifocal means two focuses literally. Multifocals are eyeglass lenses that enable you to see clearly at two different distinct distances while only using one lens. Benjamin Franklin has been credited with inventing the first bifocal lens by cutting two lenses in half from two different lens prescriptions and gluing them together. The top half was used to see greater distances while the lower half assisted greatly with viewing objects and text within arm's reach.
Bifocal glasses are used for many reasons, but the most common reason is Presbyopia. Presbyopia is a vision condition in which the crystalline lens within the eye looses its flexibility thus hampering the ability to focus. One may need a multifocal lens simply due to age.

IV. Coating Choice

Semi Finish 1.59 Index Lenses , 70MM Dia Round Top Polycarbonate 1.59 Lenses Blanks

Hard Coated(HC): To enhance the hardness of the lens to prevent the substrate scratch

Hard Multi Coated(HMC/ AR): To protect the lens effectively from reflection, enhancing functional and charity of your vision
