Yes. Every Kelvin lens is rated UV400 and blocks 100% of UVA and UVB rays.

Polarized lenses filter horizontal light reflected from water, roads and glass. The result is less glare, deeper colours and less eye strain. Polarized styles are marked on each product page.

They filter part of the high-energy blue light emitted by screens and reduce glare, for more comfortable long sessions at the desk. They are comfort eyewear, not a medical device.
