Greasy goggles
🕑 Added 2018-07-06 09:58:05 +0000 UTC Two words that are used together rarely...The nice glass-lensed UVEX pair from Mr. Hightechstuff is a fine pair of protective eyewear, but better suited for higher wavelengths. So I got another pair from a surplus shop and sure enough: Smells like an old army depot and is extraordinarily greasy. BUT: OD14 at 1060 14 at 840 nm NEODYMIUM-GALLIUM ARSENIDE it says on the plastic lens. Seems good for my 977 nm laser?

@1:50 it actually looks like an external coating has started to flake off the glass - perhaps attacked by the grease?

Just use liquid soap and some warm water. That cleans off most things. Especially Dawn dishwashing liquid.

Ewwwww. Hope it comes off with rubbing alcohol or another easily accessible home good 😷
