 Single vision lenses have one single prescription across their entire surface and are suitable in all scenarios, whether you need your glasses for driving, working or reading. |  Lenses can be made of various materials of varying weight and thickness – the overall result depends on the density of the lens material as well as your personal prescription. As a general rule, if you are long sighted your lenses are thickest in the middle, and the opposite is true if you are short-sighted, the lenses are thickest at the edges. |
 For athletes and sports applications, we highly recommend the Polycarbonate Lenses. Polycarbonate is virtually unbreakable, and it is used exclusively by many of the world's finest sports glasses manufacturers and optical laboratories. |  Eyes change throughout our lives, gradually losing the ability to focus on close objects. During our mid-forties, the lenses in our eyes become stiffer, and the muscles that control them change - which eventually causes blurred vision. This is called Presbyopia. |
 All sunglasses are designed to reduce brightness, but glare from the sun can still cause eye strain, squinting or even temporary blindness – which can be particularly hazardous while driving a vehicle. To avoid this, Optical Masters recommends polarized lenses, which provide 100% protection from glare and block 100% of harmful UV rays. |  Other than progressive multifocal lenses, we carry a wide variety of multifocal lenses including bifocal and trifocal line mutifocals. |
 Genuine Transitions® Lenses are satisfying millions of spectacle wearers across the world. With the widest variety of lens designs and materials to choose from, Transitions adaptive lenses offer a distinct advantage over ordinary clear lenses.“Transitions is a registered trademark of Transitions Optical, Inc.” |  The curved surface of glasses lenses, along with the materials they are made from, cause reflections. In fact, you can lose around 10% of light through reflections on lenses. These reflections can be distracting and appear unattractive. An anti-reflective coating allows for clearer vision by reducing reflections. |
