I didn't need anything fancy and expensive for my work area. I sand plastic parts and there's times a pieces of flash goes flying into my eyes and/or just plastic dust. Wearing these makes my life easier and safer. I was hoping correctly,no distortion visual looking through them. Besides,I have to be detailing my parts and be able to see every flaw is removed.
Currently,I haven't experienced any fogging,maybe cause I don't wear them to tight around my head. Tho' I do clean the lens with my spit and them rinse off with tap water. Helps with the fog.
