LotuTec® is the innovative ZEISS spectacle lens coating that helps you to enjoy clear vision at all times. The water and grease-repellent coating displays a strong beading effect that significantly simplifies cleaning.
The Super ET broadband anti-reflective coating eliminates irritating glare and reflections. The hard coating makes the lens surface tougher.
As with some plant leaves, fluid and dirt particles gather on the surface of the lens.
As with lotus leaves, fluid and dirt simply drip or fall off the lens thanks to the Clean Coat of LotuTec®.
More than good durability
LotuTec® sets pioneering standards in durability. Wearers will enjoy a totally new experience in wearing comfort - thanks to the lotus effect of Clean Coat.
Principle invented by nature
A principle of nature inspired us to invent the outstanding Clean Coat - the lotus effect.
Simply clean - simple to clean
Fluid and dirt simply drip or fall off the lens. Cleaning and lens care are much easier if the lens does get dirty.
ZEISS lenses with LotuTec® AR coating are durable lenses as they are provided with a hard lacquer.
2. Dirt resistant
Thanks to the ultra-smooth Clean Coat, dust and lint do not adhere to the surface easily.
3. Very easy to clean
The super-slick Clean Coat makes lenses very easy to clean. Lenses with high contact angle repel oil and water more effectively.
4. Anti-reflective properties
Green reflection colour provides good anti-reflective properties.

To offer patients true protection, ZEISS has developed an additional anti-reflective layer on the back of the lens, reducing the indirect light reflected into the eye and complementing the protection offered by ZEISS UVProtect Technology in all clear plastic lenses which blocks direct UV rays from the front.
More than 90% of UV radiation comes directly from the front. However, a minor part comes in indirectly from the sides and back. As some UV rays may be reflected onto the eye by the back surface of the lens, ZEISS antireflective coatings are designed to have low reflectance in the UV spectral range.
Back surface UV protection is now integrated as a standard feature into all premium ZEISS DuraVision coatings and the LotuTec coating.
