LENSES AND ITS TREATMENTS

Prescription Lenses Treatments

Pro-Vision offers a wide array of different lens treatments for your prescription lenses, that will provide you with a lens fit for any environment. You are able to choose from several different anti-reflective coatings, hard coatings, tinting, polarized lenses, as well as Transitions lenses. Each lens is of the best quality and is available to you at an incredibly price.

Anti-reflective

Anti reflective coating (also called "AR coating" or "anti-glare coating") improves vision, reduces eye strain and makes your eyeglasses look more attractive. These benefits are due to the ability of AR coating to virtually eliminate reflections from the front and back surfaces of your eyeglass lenses. With reflections gone, more light passes through your lenses to optimize visual acuity with fewer distractions (especially at night), and the lenses look nearly invisible — which enhances your appearance by drawing more attention to your eyes and helping you make better "eye contact" with others. AR coating is especially beneficial when used on high-index lenses, which reflect more light than regular plastic lenses. Generally, the higher the index of refraction of the lens material, the more light that will be reflected from the surface of the lenses. Scratch-Resistant Coating

No eyeglass lenses — not even glass lenses — are scratch-proof. However, lenses that are treated front and back with a clear, scratch-resistant coating have a much harder surface that is more resistant to scratching, whether from dropping your glasses on the floor or occasionally cleaning them with a paper towel.

Kids' lenses, especially, benefit from a scratch-resistant hard coat for greater durability. Anti-Fog Coating

If you live in a cold climate, nothing is more frustrating than having your eyeglasses fog up when you come in from the cold. This also can be a safety issue, since it limits your ability to see until the fog clears. Lens fogging can be especially dangerous for police officers and other first responders to emergency situations. At least one eyeglass lens coating company (Opticote) has created a permanent coating designed to eliminate this problem. The factory-applied coating — called Fog Free — eliminates the condensation of moisture on lenses that causes fogging.

So your lenses and vision stay clear when you make the transition from a cold environment to a warm one. It may also keep your lenses from fogging up during sports and other times you are hot and perspiring.

Ultraviolet Treatment

Another beneficial lens treatment is an invisible dye that blocks ultraviolet (UV) light. Just as sunscreen keeps the sun's UV rays from harming your skin, UV-protective treatments for eyeglass lenses block those same rays from damaging your eyes.

Overexposure to ultraviolet light is thought to be a cause of cataracts, retinal damage and other eye problems. Regular plastic eyeglass lenses block most UV light, but adding a UV-blocking dye boosts UV protection to 100 percent for added safety. Other eyeglass lens materials, including polycarbonate and most high-index plastics, have 100 percent UV protection built-in, so an extra lens treatment is not required for these lenses.

Photochromic lenses also block 100 percent of the sun's UV rays without the need for an added UV lens treatment. Photochromic Lenses

Photochromic lenses are clear indoors and darken automatically in sunlight for greater comfort in different lighting conditions. Transitions Optical makes the most popular brand, which has led some people to call all photochromic lenses "transition lenses" or Transitions lenses.

Xperio Polarized Sun Lenses

Xperio is a new brand of polarized sunglass lens from Essilor, the world's leader in prescription lenses. Xperio lenses are available with any type of prescription strength.
