If you have a stronger eyeglass prescription, your optometrist may have mentioned high index lenses at some point. If you’re wondering what these are or thinking you may need high index lenses, we have an explanation for you.
What Are High Index Lenses?
Eyeglass lenses correct the wearer’s eyesight by bending light as it passes through the lens glass. How much the lens bends the light is called the lens power, and this is what your eyeglass prescription usually indicates.
Most eyeglass wearers are nearsighted, meaning their lenses are curved with thin centers and thick edges. The stronger the prescription, the thicker the edges. For people with particularly strong prescriptions, this can result in the infamous “bottlecap” lenses, with particularly thick edges that are cumbersome and aesthetically unappealing. With today’s modern styles featuring thin rims, these thick lenses are even more problematic.
High index lenses essentially have more light-bending power than normal eyeglass lenses. This means thin high-index lenses can have the same lens power as a pair of bottlecap lenses. The result is a pair of lenses that are thinner, lighter, and more aesthetically pleasing than traditional lenses.
When to Use High Index Lenses
High index lenses are the best choice for those with particularly strong eyeglass prescriptions, whether they are nearsighted, farsighted or have astigmatism. These high index lenses prevent them from having particularly heavy or thick lenses.
High index lenses are also a good choice for people who are particularly sensitive to weighty glasses and want their eyewear to be as light and comfortable as possible. It is worth noting, however, that higher index lenses tend to cost more.
If you’re wondering, “Do I need high index lenses?” talk to your eye doctor to choose the right index for your visual and budgetary needs.
