We like to refer to our Sunfast product as a “superlens”. Sunfast lenses are manufactured exclusively for Optica Omni, using a special type of polycarbonate that results in lenses that are thinner, lighter and stronger than most on the market. It offers UV protection up to 400 nm, the maximum wavelength for ultraviolet light (most lenses only protect up to 100nm). Sunfast lenses are hydrophobic, which means they repel water, like the bodywork of your car after it has been waxed. They are also oleophobic, which means they repel grease. Owners of the iPhone 6 will be familiar with this technology, as the screen is also oleophobic, allowing you to wipe away fingerprints quickly and easily. Sunfast lenses feature an anti-reflective element that is actually built into the lens, giving you comfort and protection from glare, without the risk of the coating cracking over time. The lenses also feature anti-scratch technology. Clarity lenses are available as both clear and photochromic lenses (SunFast), as well as Freeform lenses.
