Product Description
Are you particularly exposed to dust or dirt at work or when pursuing your hobby? Are you a big fan of the purity and optical performance of mineral lenses? Or do you attach a great deal of importance to the durability of your lenses? Then mineral lenses may be a solution for you.
Plastic lenses are obviously the first choice for sports glasses or children's spectacles, as they are lighter and more shatter-proof. But it is no coincidence that precision optics, such as camera, microscope and telescope lenses, and the touchscreens on modern smartphones are made of mineral glass. Glass provides a highly durable, smooth and scratch-proof surface, helping to prevent fine scratches developing on the lens in dusty surroundings.
What is more, high refractive indices allow thinner, more slender lenses to be produced, making you look more attractive and your eyes more natural - even with higher prescriptions.
What makes mineral lenses so durable?
Schematic diagram of the molecules in a mineral lens - left - compared with the unstructured molecules of a plastic lens - right.The secret of mineral lenses lies in the strong material cross-linkage and the molecules' dense 3D structure. This guarantees a long performance life because the hard, smooth surface stops fine scratches from developing in the first place.
