Mineral glasses are made from "real glass", they are known for their durability and high image quality. As a good alternative to plastic glasses, they offer the following advantages:

• Highest image quality
• Very scratch-resistant due to high surface hardness
• Long lifetime
• Thin glasses for severe ametropia
• Good environmental compatibility in the manufacturing process
• Very easy to clean

The glasses can be manufactured with conventional manufacturing technology or with Swiss HD technology. The Swiss HD technology is the most accurate manufacturing technology for a spectacle lens.

The combination of the material and the manufacturing technology gives the spectacle wearers excellent image quality and high contrast vision.
