The 1.61 high-index lenses are typically made from a polymer material known as "polycarbonate" or a specific type of plastic, like Trivex or MR-8. These materials are lightweight, durable, and have superior optical clarity.

High-Index Material: These lenses have a higher refractive index (1.61) compared to regular plastic lenses (which typically have a refractive index of 1.50). This means the lenses can bend light more efficiently, resulting in thinner and lighter lenses, even for individuals with stronger prescriptions.

Clear Vision: They provide excellent optical clarity and visual acuity, making them a great choice for everyday use.

Durable: Typically coated with scratch-resistant coatings, these lenses are designed to resist daily wear and tear.

>UV Protection: Many 1.61 lenses come with built-in UV protection to safeguard your eyes from harmful ultraviolet rays.
