High Index Lenses: 1.61 vs. 1.67 vs. 1.74

Embarking on a journey to enhance your vision often involves navigating through various lens options. High index lenses, in particular, stand out as a technological advancement designed to provide a sleeker and more comfortable eyewear experience. In this exploration, we’ll delve into the benefits of high index lenses and unravel the distinctions between 1.61, 1.67, and 1.74 high index lenses. At Zenni Optical, we’re proud to offer all three levels of high index lenses, ensuring affordability without compromising on quality.

Understanding High Index Lenses

High index lenses are engineered to address the visual needs of individuals with higher prescriptions. The term “index” refers to the refractive index of the lens material, which measures how efficiently light is bent as it passes through the lens. The higher the refractive index, the thinner and lighter the lenses can be, resulting in a more cosmetically appealing and comfortable eyewear experience.
