Eyeglass Lens Coatings Options and Its Features


Anti-Reflective coating

Anti-Reflective coating eliminates light reflections and complements the readability and comfort in all light conditions without reducing their sun-reactive performance. The visual benefits of lenses with anti-reflective coating include sharper vision with less glare when driving at night and greater comfort during prolonged computer use when compared with wearing eyeglass lenses without
AR coating. Anti-reflective coating to eyeglass lenses is a highly technical process involving vacuum deposition technology. Generally, AR coating is applied only to the back surface of sunglass lenses because there are no cosmetic or visual benefits to eliminating reflections from the front surface of dark-tinted lenses. Most premium AR lenses include a surface treatment that seals the anti-reflective layers and makes the lenses easier to clean. Modern anti-reflective coatings can virtually eliminate the reflection of light from eyeglass lenses, allowing 99.5 percent of available light to pass through the lenses and enter the eye for good vision. Relying on the AR coating components, most lenses with anti-reflective coating have a very faint residual colour, green or blue, that is characteristic of that particular brand of the coating.

Scratch-Resistant Coating

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. Now-a- days most eyeglass lenses, including high-index lenses and lenses made of polycarbonate and Trivex, have a built-in scratch-resistant coating. The best scratch-resistant coating can’t completely protect your lenses from wear and tear. Because no eyeglass lens is scratch proof, the coating only acts as a resistance. To keep your glasses looking new, store them in a cushioned case when not in use, and clean your lenses with a microfiber cloth and the cleaning solution your optician recommends. Since scratch-resistant coatings are sometimes optional, make sure your optician knows that you want your eyeglass lenses to include hard coating for extra durability.

Anti-fog Coating

Anti-fog coating is also known as non-mist coatings. The humidity creates more moisture, which can form fog. Anti-fog lenses are available in plastic, polycarbonate and high-index plastic lens materials. An anti-fog coating that chemically bonds well to the surface of one plastic may bond only loosely to another, which means it will be washed off more easily by humidity and perspiration.

Ultraviolet protection

UV radiation from the sun can damage your eyes. Ultraviolet protected eyeglass lens blocks ultraviolet (UV) light that damaging your eyes. Overexposure to ultraviolet light is thought to be a cause of cataracts, retinal damage and other eye problems. AusSpecs strongly recommend you to wear sunglasses whenever you are out. Sunglasses are excellent protective gear and therefore, you must use them throughout the year. Further, snow reflects a lot of light which can make it difficult for you to see clearly and can even strain your eyes. They also protect your eyes from cold wind that can dry them out.
