Chart showing different types of lenses available from C Mor Safety

The section below includes information about lenses and options available for your program through C-Mor Safety. We hope it will give you a better understanding of our products, services and program options for prescription safety glasses. Please contact us with any questions you might have.



Single Vision
Single vision lenses are prescribed to correct one field of vision for distance, intermediate (computer), or items up close (near vision). Single vision lenses have the same optical focal point or correction over the entire area of the lens.


Bifocal Lenses

Bifocal lenses have two optical focus points; the upper part of the lens is generally used for distance vision, while the lower part is used for near vision. Usually, a segment line separates the two. Typically a person with myopia would have one section of a prescription lens that has a certain diverging power while another section of the lens would have a lower diverging power for close-up work. Similarly, a person with hyperopia would have one section of the lens with a certain converging power and another section with a greater power for close-up work.


Trifocal Lenses

Trifocal lenses are similar to bifocals, except that the two focal areas are separated by a third middle area with intermediate focus correction. This area is used for intermediate vision; roughly at arms’ length, e.g. computer distance. This lens type has two segment lines, dividing the three different correcting segments.


Progressive Lenses

Progressive lenses provide a smooth transition from distance correction to near correction, eliminating segment lines and allowing clear vision at all distances, including intermediate; roughly arms’ length.


Occupational Lenses

Occupational lenses allow the wearer to view all working distances, side to side, up and down, within a conventional working distance, or small environment.  A working distance typical to many occupations will fall somewhere between ten to thirteen feet, respectively.
Our working and lifestyle environments require that we have clear vision at working distances of 1.5, 2.5 and out to 10 feet.  This vision must be clear in all areas of the lens and at all viewing angles.


Polarized lenses

Polarized lenses have an embedded chemical film that creates “slots” through which light can pass. This process reduces glare and eliminates harmful UV light.


Transition/Photochromic lenses

Transition/Photochromic lenses darken automatically when exposed to sunlight, then fade back when you return indoors.


Anti Reflective Coating

Anti Reflective Coating (ARC) eliminates glare and allows more light to pass through your prescription lenses. Reducing glare is beneficial for many reasons. Not only does AR coating eliminate reflection that others may see on the surface of your lens, but also greatly reduces the glare from computer screens, lights at night and from fluorescent lighting indoors.



TD2 (Tough, Durable, and 2-Sided) coated lenses offer a superior, warranted protection against scratching on our prescription safety lenses. Integrating glass-like silica particles into a polymer matrix, TD2 serves as the base coating for AR Coat and OptiFog coated safety lenses. Polycarbonate lenses coated with TD2 are more scratch resistant than ever providing consistent protection and durability.



Optifog lenses have unique, hydrophilic top layers with inherent fog repellence properties. The anti-fog top layers placed on the Optifog lens are activated with the Optifog Activator Cloth. The Optifog Activator Cloth has the power to ACTIVATE and CLEAN the lens at the same time. Just use the Optifog Activator Cloth whenever you clean your lenses. Together they provide fog-free vision by spreading fog into a uniform, invisible layer of water on the lens surface.
