Our Lenses

Our custom filter lenses immerse you in a world reminiscent of a distinct time, place or feeling - an experience you’ll want to revisit time and time again. All lenses are developed with our optical experts in France and exclusively custom dip dyed to Tens specifications. They’re scratch resistant and provide 100% protection from UVA and UVB light; blocking all harmful rays while offering a unique viewing experience.


Our sense heightening lens tints are featured in premium, handcrafted frames which are designed in our studio in Scotland. Each frame is specifically designed to deliver a superior fit, finish and balance. Constructed from optical grade Italian acetate or lightweight, brushed stainless steel and including both five and three barrel hinges; Tens are a durable and wearable pair of sunglasses to own.


Got a question?

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

Our Original lens is a Category 3 tinted lens featuring full UVA and UVB protection, and 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?

We have spent years working with our suppliers to create a perfect, sense-heightening tint. Custom designed and dip-dyed, the rich red-amber tones of Tens Original lens is designed to add warmth and natural colour definition in high-mid and low-light conditions and tonal environments. 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?

Designed in Scotland and developed with our dedicated friends and supply partners in France, Italy and Hong Kong our frames are made from plant-based acetates sourced through selected suppliers including Italy's Mazzucchelli. Our lenses are produced using optical-grade and hi-clarity CR39 material dip-dyed to Tens specifications. Additionally our high quality Italian components include metal core-wiring allowing all frames to be hand-adjusted.
