What type of lenses can provide protection against UV radiation?

Polycarbonate lenses are known for their inherent ability to provide protection against UV radiation. This material not only offers a lightweight and impact-resistant option but also incorporates UV protection directly into the lens itself, eliminating the need for additional coatings. The protective properties are built into the lens, making polycarbonate an excellent choice for individuals looking for eyewear that safeguards against harmful UV exposure.

High index lenses, while they are designed to be thinner and lighter than standard plastic lenses, may not necessarily offer UV protection unless they have specific coatings added. Standard plastic lenses typically require a UV coating to provide the same level of protection, and reading glasses are primarily designed for magnification without any guaranteed UV protection unless specified. Thus, polycarbonate lenses stand out as the superior option for UV protection in eyewear.
