HI INDEX EYEGLASS LENSES
Hi-index eyeglass lenses are designed to offer prescriptions in a thinner, more lightweight plastic material.
Ideal for people with higher prescriptions that result in thick heavy lenses, hi-index lenses can also provide much better vision compared to traditional plastic lenses.
Most hi-index lenses also include an aspheric lens design. Aspheric lens design helps improve vision quality throughout the lens and also helps reduce the magnification or minification, or the bugs-eye appearance.
There are many different forms of hi-index lenses. The lenses index of refraction, or the ability of the lens to bend the light, is what varies from lens to lens. A lens with a higher index of refraction has the ability to be much thinner and lighter than a lower index of refraction.
