Tocmai am gasit doua articole despre fungii care se stabilesc pe lentile si care efectiv le pot strica suprafata.
Sunt prezentate de asemenea si masuri prin care acestia pot fi indepartati. Este citata si apa oxigenata.

Mai jos va dau linkurile catre cele doua articole si va prezint si un mic citat :

" One problem is that even if the fungus is dead, and is itself completely removed, they can leave a deposit behind which is very firmly attached to the lens. This is often mistaken for etching damage. 
Hydrogen peroxide, or bleach, can be used to kill fungus. According to Leitz, a fungus treatment of 94% distilled water, 4% clear ammonia, and 2% hydrogen peroxide should be used. The lens element should be soaked in the mixture for an hour or more before cleaning.
The hydrogen peroxide is included in order to destroy any fungal spores, and hyphen but unless the whole of the lens including the housings etc. is treated, it is difficult to see that much benefit will be gained. It does however make an effective cleaner. 
Many report that household spirit vinegar can be effective for lens cleaning. Given that it has marked anti fungal properties, and easily obtainable I would recommend giving it a try. "
