I've tried several anti-fog products in the past, but Clartherm's solution is by far the best. The effectiveness of the product is impressive, and it works equally well on different types of eyewear. The fog resistance lasts for a long time, and I don't have to worry about fogging up during outdoor activities anymore. Overall, I'm extremely satisfied with Clartherm antivaho, s.l.'s anti-fog product!
