What is a key benefit of using Trivex lenses?

Increased scratch resistance
Better cosmetic appearance
Significantly lighter and durable
Available in higher prescriptions only

The correct answer is: Significantly lighter and durable

The key benefit of Trivex lenses being significantly lighter and durable stands out due to the unique material properties of Trivex. This material is known for its lightweight nature, making it an excellent choice for individuals who prefer comfortable eyewear that doesn't add significant weight to their frames. Additionally, Trivex is engineered to be impact-resistant, providing enhanced durability compared to some other lens materials. This is especially advantageous for active individuals or those in occupations where eyewear may face potential hazards. While increased scratch resistance and better cosmetic appearance are also important considerations in selecting lenses, these factors do not define the standout characteristic of Trivex. The mention of higher prescriptions applies to other materials and does not highlight what makes Trivex particularly appealing to a broader audience. The lightweight and durability aspects make Trivex a compelling option for many eyeglass wearers.
