If glasses distort your vision, it results in headaches and fatigue. Therefore, with all of Filtral’s sunglasses and reading glasses we ensure the highest surface quality without streaks, inclusions or air bubbles.

Thanks to the hard lacquer sealing, scratch resistance is increased significantly and lenses do not become opaque due to scratching.


The lenses used provide distortion-free vision and therefore also ensure accurate perception.
