Previously, people always need to wear thick lenses if they have a strong prescription, these lenses are absolutely uncomfortable to wear and they reduce the confidence of the person who is wearing them, actually, people wearing prescription glasses were considered away from the fashion kingdom, that’s the reason why so many people wear “zero-Rx” eyeglasses just for fashion nowadays, and now, trendy and light weight prescription eyeglasses lenses are available for people who need to correct their strong Rx, it is today’s main topic: high index lenses!

These lenses are made by material which has high index of refraction, the higher the refractive index is, the thinner the lens will be. It is the dense and hence lesser material that used in high index lenses. They have great optical quality just as conventional prescription eyeglasses plastic lenses, but they are of light weight compared to the later. There are two properties required in prescription glasses lenses: the refractive index and the curvature. If we need the lens to be as thin as possible, the refractive index should be higher, while the curvature should be minimum, that’s why high index lenses can bend more light and leading to thin edges.
What’s more, these prescription eyeglasses lenses are not only suitable for people who were suffered from myopia, but also fit for person who wear minus power, and high index prescription lenses even have great advantages for these people, as in ordinary Rx lenses, the thinnest part of lenses is at the center and the thick edges will not be visible because of the frames, but we cannot do this in reading eyeglasses lenses, which has a thick center than the edge, so, that’s the reason why we need aspheric lenses, which are mostly made of high index material and they serve the cosmetic purpose.

All in all, the main purpose of wearing these lenses is for clear vision, you can choose to wear high index prescription eyeglasses no matter if you are suffered from myopia or hyperopia, these lenses will give you the look of an elegant chic, probably, the only disadvantage of such lens is its price, usually, we cannot get a pair less than $250 at local eyeglasses stores, I suggest you can try them at online site, which also have quality high-index lenses, but the price is much cheaper, and the last point, you can order a separate scratch resistant coating for these lenses, they can guarantee a anti-scratches protection!
