ZEISS LotuTec coating

Lotus flower effect
A principle from nature: The lotus flower effect.That is the water repelling characteristic of surfaces, to simply let water drops pearl off and to repel dirt. LotuTec acts as protective coating and cleaning and care is made especially easy.
This technology has been used by Carl Zeiss for millions of spectacle lenses for a long time.

collect on the surface and adhere.
