As a follow-up to one of my evergreen posts (according to my visitor stats), I ought to write about this Zeiss anti-fog spray and cloth.

I wanted to try this back when I tried the others, but it wasn’t in stock, and then I forgot about it etc. Well, now we’re back wearing masks a lot of the time (I never stopped wearing them in shops), anti-fog technologies are back on the agenda.

This, my friends, is really good and very effective. Make sure your glasses are clean, then spray each lens on both sides and dry off with the cloth.

Unlike the standalone cloths, which require frequent reapplication, this Zeiss kit works for days on end. You only need to reapply when your glasses are filthy and you have to clean them again.
