Polycarbonate: Polycarbonate (impact-resistant) lenses are shatter-proof and provide 100% UV protection. They're also ideal for strong prescriptions since they do not add thickness when correcting vision, minimizing any distortion.

What does polarization mean?
Sunlight scatters in all directions. But when it strikes flat surfaces, the light that is reflected by the surfaces tends to become polarized — meaning the reflected light beams travel in a more uniform (usually horizontal) direction. This creates an annoying and sometimes dangerous intensity of light that causes glare and reduces visibility.
Polarized lenses have a special filter that blocks this type of intense reflected light, reducing glare and discomfort.

Photochromic: A photochromic lens is an optical lens that darkens on exposure to light of sufficiently high frequency, most commonly ultraviolet (UV) radiation. In the absence of activating light, the lenses return to their clear state.
UV-400: 'UV400' refers to UV rays at the top end of the UV spectrum, up to the 400-nanometre wavelength. Sunglasses with this level of protection block an even wider spectrum than the CE and British Standard models, making them the ultimate protection for your eyes.
