Does our Tens lens protect your eyes from harmful rays and are they polarised?

Our signature lens is a Category 2 tinted lens featuring full UV400 protection, blocking 100% of harmful rays. Our sunglasses aren’t polarised. The reason for this is that our perfect lens tint is not possible whilst being polarised. Our lens provides a clear and balanced view filled with depth, which makes Tens very comfortable to wear whilst driving.


What makes our Tens lens special in comparison to other lenses?

We have spent years working with our supplier to create a perfect, sense-heightening tint. To our knowledge, there are no other sunglasses available on the market that will offer you as pleasurable a view as Tens.


Are Tens available with prescription lenses?

Unfortunately we don’t currently offer a prescription version of Tens, but it’s certainly something we wish to provide in the near future. Keep in touch via our social networks for updates!


What size are Tens, and are they unisex?

All of our frame styles are suited to both guys and girls! The exact measurements and technical specifications can be found by selecting or scrolling down to “Size Guide / Technical Details” on each individual product page.
