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

FAQ toggle open/close

Our Original lens is a Category 3 tinted lens and our Spectachrome lens is a Category 2 tinted lens. Both feature 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 with the addition of polarisation filters. Our lens provides a clear and balanced view filled with depth, which makes Tens very comfortable to wear whilst driving and participating in sports.

What makes the lens special in comparison to other lenses?

FAQ toggle open/close

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.

What are your frames made from?

FAQ toggle open/close

Our “Core Collection” frames are made from regular acetate. Like our “Bio Collection” it is a hypoallergenic and durable material made from cotton and wood pulp.

Is the “Bio Collection” a completely biodegradable product?

FAQ toggle open/close

The frames from our “Bio Collection” are 100% biodegradable and our mission by 2020 is to transition our whole product offering using this material. The frame can biodegrade in 115 days when the pulverised material has been put into a compost environment with controlled conditions.

Our packaging is made using recycled and biodegradable materials, and we no longer use plastic sleeves to wrap the product. Whilst our lenses are currently made using an industry-standard plastic polymer, we are investing significant efforts into a bio-based solution to disrupt the industry. We aim to replace these and our metal wire core with a more bio-friendly solution in the near future.
