TPX (Polymethylpentene): it’s the lightest polymer frame . Thanks to his 0.83g. density the glasses will float when dropped in water to prevent loss from sinking sunglasses. Resists lotions and absorbs extreme impact.
TPX material offers flexibility and lightweight floating ability. Polarized lenses reduce the light into one direction and cut out the unnecessary light which disturbs the vision. This way you can obtain a better contrast and you do not have to reflections; the images are sharper and so the perception of the vision is better , making your vision relaxed and safe.
