Click:86 Time:2020-03-09


With focus on increasing the use of sustainable materials in its production, Dalloz Creations®, inventor of the patented CRIDAL® SUN LENS material (BPA & Phthalate free lens material) has announced the launch of a new Bio-based lens material: BioNylon.

Dalloz Creations is committing to a more sustainable approach in its production lines and choice of materials. The new BioNylon material by Dalloz Creations is made from an ecological resin derived from castor oil, taking its energy from the bio-mass. The castor plant grows in semi-arid areas and does not compete as a food crop. The production process requires less energy than the production of a classic lens, and contributes to the reduction of CO2 emissions thanks to its purified resin quality.




BioNylon material is a highly developed polymer from organically based, renewable raw material made out of castor bean. The eco-responsibility in this material can be seen at many levels. The seeds grow in semi-arid conditions following sustainable farming practices. This crop does not compete with the food chain for humans or animals.

The castor seeds, which provide the main source for the lens material are transformed into pellets and then injected into the lens. The material is resistant to a broad range of chemicals and to stress cracking. To achieve excellence, we have worked hard to match outstanding optical clarity. The results are there and the material is now available in most of Dalloz Creations’ colours and dimensions complying with international standards.


This material is mostly appreciated for its low carbon footprint, easy processing, chemical and fatigue resistance and excellent optical quality. BioNylon lenses will be presented by fashion and sports brands very shortly. “This new bio-based material is a step further on the way to sustainability and a belief in a better future”
