Nope, standard welders mask won’t do the trick. Most are level 12, solar viewer evidently has to be a 14.
HUMAN SAFETY #1
Oops. Prior poster gave very dangerous advice.
In other words,
DO NOT USE WELDER’S GLASS !!
If you order the wrong number, or they mistakenly deliver wrong number, you are SCREWED !
Instead use only clearly labeled cardboard glasses and double check their website. Even better, only oblique reflected, no mirrors.
NEVER MESS WITH LIFE OR LIMB !
Take the advice of a true Engineer. :-)
There, I may have saved one person’s sight today.
