What Are High-Index Lenses?

Whether you are an eyeglass wearer or not, it’s highly recommended to visit your optometrist at least once a year to check on your eye health and vision. In some cases of stronger eyeglass prescriptions, you might be offered to use high-index lenses instead of the regular lenses.

In this post, Nova Vision Center shares some basic information about high-index lenses. Find out below if these lenses would suit your needs.

High-Index Lenses: How Do They Differ From Standard Lenses?

Traditional plastic lenses that are used for high amounts of nearsightedness or farsightedness are usually thick and heavy, which can make it uncomfortable for some people to wear glasses. Fortunately, high-index lenses are designed to bend light more efficiently with less material. This means that they can correct the same amount of refractive error while also being thinner and lighter than the standard glass or plastic lenses.

High-index lenses typically have an aspheric design as well. This enables them to be slimmer than traditional lenses and to reduce the “bug-eye” look that is common with high-prescription conventional lenses.

Who Can Use High-Index Lenses?

The benefit of high-index lenses mainly depends on your prescription. If you have a prescription lower than %20/- 2.00, you won’t experience any significant difference or added benefit by using high-index lenses. However, if your eye doctor determines that your prescription is higher than %20/- 2.00, you can definitely feel the difference when you switch to high-index lenses.

Take note, though, that high-index lenses cost more than standard lenses. So if the benefit isn’t noticeable, you’re better off sticking to traditional lenses. To further help you decide on whether to get high-index lenses or not, it’s best to consult your eye specialist.
