What is the name of Oakley's impact-resistant lens material?

Oakley’s impact-resistant lens material is called Plutonite.

Plutonite is Oakley’s proprietary name for the optically pure polycarbonate material used in its sunglass lenses. Polycarbonate is the broader material category, while Plutonite is the Oakley-branded lens formulation and technology. That distinction is why “Polycarbonate” is related but is not the best canonical answer to this question.

The material is valued for combining low weight, optical clarity, and resistance to impact. Oakley also says its Plutonite lenses provide inherent protection against ultraviolet light, rather than relying only on a surface coating. Lens shape and frame geometry work with the material to support the overall protection of the finished eyewear.

A common mix-up is treating Plutonite as a coating like Iridium. They serve different roles: Plutonite is the lens material itself, while Iridium is a reflective coating applied to a lens. Polarization is another separate lens feature designed to reduce glare from reflective surfaces. Oakley’s early sport eyewear helped establish this technology-focused approach to sunglasses.
