I don't have any solar eclipse glasses /diy/ so I want to use sunglasses. But not just one, but a lot!

I'm tyring to figure how if there is a rating for welder goggles, because it's recommended that you use Welder goggles #14. However I honestly can't find any real mathematical measurement that determines the shade value of these various googles so I can find how many pairs of sun glasses are required to mimic the solar eclipse goggles or #14 welder goggles.

I don't want to look in a box to see a white dot move. I can watch a white dot in a box move around anyday

Dude just go to harbor freight or lowes , home depot and get some welders goggle, they're like five bucks.

Ex-CWI, a shade 14 is pretty rare, usually Mechanized GMA Spray or Air Arcing, so are usually special order. Also, if you do find one, like in an old tool box, you gotta make sure its not scratched.

You can't take a no. 10 and a no. 4 combined its not the same.

The ones sold at most places are like No. 10 or 11 so watch out for the ones you buy at reputable places. Harbor Freight I would avoid at all costs.

>13 or darker is safe enough. Also, you CAN add up welding glass, using the formula S(sum) = S1 + S2 -1. S(sum) should be greater than or equal to 13

I plan to stare at the sun all day to get on neetbux and disability.

I've just purchased a space blanket at the local Dollar tree, cut out a section and folded it up 2 or three times. Sunglasses underneath to protect against uv, and you've saved your money from the jews

Fuck off retard. This eclipse has been predicted down to the millisecond since before you were born. If you couldn't be bothered to pick up a $2 pair of viewing glasses before they all went out of stock you can get fucked.

It was less than $60 for the pair of 10x solar binoculars I bought, and as soon as the eclipse if over I just unscrew the filters and then have a pair of regular binoculars. But that's because I have the ability to plan ahead more than the next 3 days of my life.

Dumbass, you're going to go blind AND you've given your money to the spaceblanket jews.

>All these people going blind
Do I just have better eyes than anyone?
I look at the sun all the time and haven't gone blind.

Don't stare at it for the whole 20 minutes, fuck.
I've even been through partial eclipses in my childhood.

Everyone is running around like their eyeballs are going to fall out.

just squint
