Materials & Sustainability

Sustainable Materials in Eyewear Care

From recycled PET in microfibre cloths to the question of whether synthetic textiles are really the more eco-friendly choice: an overview of materials in eyewear care and what actually makes them sustainable.

Why material matters for eyewear care at all

Not every cloth is suitable for sensitive lenses – fabric type, fibre fineness and cleanliness of the cloth all affect whether a coating is protected or damaged. At the same time, what such cloths are actually made of is increasingly coming into focus from a sustainability perspective.

rPET as an alternative to virgin polyester

Recycled PET (rPET) is obtained from already-used plastics – mostly PET bottles – and spun into new fibres. For microfibre cloths, that means the same cleaning properties as virgin microfibre, but without extracting additional crude oil. Details on production: What is recycled PET (rPET) and how is it made?

An honest look at the environmental footprint

rPET isn't superior in every respect – one study even shows that recycled polyester can shed more microplastic when washed than virgin material.

Looking after the cloth itself
