Which of the following is a benefit of high-index lenses?

High-index lenses are designed to be thinner and lighter than standard lenses, especially for individuals with stronger prescriptions. The main benefit of high-index lenses lies in their ability to effectively bend light, which allows them to provide the same level of vision correction as standard lenses while requiring less lens material. This results in a thinner lens profile, making them more comfortable to wear and aesthetically appealing, particularly for those who may be self-conscious about the thickness of their glasses.

In contrast to the other options, high-index lenses are specifically crafted to reduce bulk and enhance comfort for wearers, rather than add to the thickness or durability concerns. While standard lenses can become quite thick for higher prescriptions, high-index lenses mitigate this issue, paving the way for a generally more flattering appearance and lightweight use. The durability aspect varies based on the specific material of the lenses, but high-index lenses can be made from durable materials too, so they do not inherently lack strength.
