Very good glasses cleaner: it immediately removes fog and steam, especially when you go from cold to warm or into humid, enclosed spaces. The anti-fog effect lasts for a very short time, not even an hour, but it makes a noticeable difference while it lasts. The question is whether it’s worth it; yes, as long as you use it sparingly, because the small bottle lasts quite a while that way. I mainly use it in winter, when I enter enclosed spaces with steam or inside the car with sudden temperature changes, and it has helped me several times to be able to see clearly.

it ruined the glasses I had for running, they had a surface film and it was destroyed even though it says it's also suitable for plastic glasses

Amazing! :) It cleans the glasses perfectly without damaging the photochromic lenses with coatings! Perfect cloth! The price is not justified... it's just a cleaner... in Germany it's very cheap. Of course, the price plays a role in such a product, that's why fewer stars.

*Attention, it says to spray the liquid on the cloth, not directly on the lens! And that's what I do.

1 spray was enough to destroy the lenses on brand new glasses and render them useless, the cloth scratches, I do not recommend it

The AVA or the lens cleaning wipes do a much better job. With this, I can clean without leaving any marks behind.

The best liquid lens cleaner. And the cloth is excellent, if you follow the cleaning instructions

Very good, cleans glasses and camera lenses perfectly. Reduces fogging on glasses, doesn't eliminate it 100% but makes a noticeable difference. I didn't expect anything less from Zeiss, one of the best companies when it comes to professional camera lenses.
