Preguntas frecuentes

¿La lente protege de los rayos nocivos? ¿Son polarizadas?

FAQ toggle open/close

Nuestra lente es una lente teñida de Categoría 3 con protección UV400 total, lo cual bloquea el 100% de los rayos nocivos. No son polarizadas. La razón es que el tinte perfecto de nuestras gafas no es compatible con los filtros polarizados. Nuestra lente ofrece una vista clara, equilibrada y con profundidad, lo cual hace que Tens sean muy cómodas para conducir y practicar deportes.

¿Qué tiene de especial esta lente en comparación con otras lentes?

Nos ha llevado años de trabajo junto con nuestro proveedor conseguir crear un tinte perfecto que realce los sentidos. Desconocemos la existencia de otras gafas de sol en el mercado que ofrezcan una vista tan agradable como la que ofrecen nuestras Tens.

¿De qué están hechas las monturas?

Our “Bio Collection” frames are made from plant-based, 100% biodegradable acetate. The material is manufactured by Mazzuchelli in Italy and derives from the renewable resources of cotton and wood pulp from a sustainably managed forest.

The impact on the environment is significantly better compared to regular plastic sunglasses which are based on petrochemical substances that burn oxygen and release CO2. The bio acetate is made from organic sources including cotton and wood pulp which have been involved in turning CO2 in oxygen through photosynthesis, and the frames themselves are 100% biodegradable. The material has undergone biodegradability test in compliance with rule ISO 14855, carried out by a paramount research institute in Belgium: Organic Waste System.

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.

¿La “Colección Bio” ofrece productos completamente biodegradables?

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 under 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.
