Which lens material is known for being the most scratch resistant?

• A. CR-39
• B. Polycarbonate
• C. 1.67 High-Index
• D. Trivex

Answer: (C)

The lens material known for being the most scratch resistant is 1.67 High-Index. This type of lens is specifically designed to be thin and lightweight while also offering enhanced scratch resistance compared to other materials. The advanced coatings applied to 1.67 High-Index lenses contribute to this characteristic, providing a durable surface that withstands everyday wear and tear. In contrast, other materials like CR-39 and polycarbonate, while they have their own benefits—such as being lightweight or impact resistant—do not offer the same level of scratch resistance as 1.67 High-Index lenses. Trivex is also known for its lightweight and impact-resistant properties, but it doesn't match the scratch resistance capability of 1.67 High-Index lenses. Therefore, when considering all options, 1.67 High-Index stands out as the best choice for scratch resistance in lens materials.
