... I have problems with moist eyes (allergic) to leave my glasses fogged from the inside, what a course the fun of reading and tinkering totally spoiled when you have to clean the glasses every few minutes, especially the old diving trick (a little saliva ) no longer helps in the present glasses. After I (as a Vorrezensentin also) have inquired at the optician to remedy, well. Due to the good meetings (thanks for that) I decided for this agent. It's great, I'm sitting now, thanks to these funds for several hours on the computer and can also use my magnifying glasses again. And it even helps against the usual fog mist to each eyeglass wearers experienced when he comes in from the cold in the heat in winter. This is a real innovation, which is a real help, and not too expensive paid, especially since even is still a very good Pflegetuch here. Will I recommend it to others who wear glasses.
