Barner Osterbro Sun Glasses - Color: Navy Blue

Superior blue light protection
We use high-quality organic CR-39 lenses that block 100% of the blue light under 410nm and 45% of the blue light on the 410nm–450nm spectrum, so you can rest assured that your eyes will always be protected.

Sustainable
Our new bio-based capsule is made using a high-performance material called Rilsan®Clear G850 Rnew®, a 45% bio-based material made from castor seeds. Once the castor plant is harvested and the seeds grinded, the castor oil is produced and later polymerized resulting in a lightweight, durable, and flexible material.

Extremely comfortable
At just 15 grams, these lightweight, ultra comfortable frames feature flexible hinges and temples for an adaptable fit and a rubberized texture for better grip on the nose and ears
