Watson sunglasses are made of added polycarbonate. Polycarbonate (PC) is a material with very high mechanical strength but with limited dynamic strength. This is why our glasses are produced by adding a percentage of ABS to the virgin PC granule, a polymer with elastic fibers that incredibly increases its resistance to twisting and bending. Furthermore, thanks to the flex temples equipped with a spring mechanism, they are comfortable and light, adapting perfectly to any type of face. The polycarbonate lenses guarantee 100% UV protection and maximum impact resistance. The result is a light but robust eyewear, ideal for everyday wear.
