#11 Welding lens

Found out it will by clear skies on Monday and want to see 64% eclipse in our area. The special glasses are sold out in our town, so we bought #11 Welding lens at Ace (we got last one; they have sold many). Hope it's $4 well spent!

I know people are saying that about the welding glasses, I don't believe it. I haven't been to the NASA sight today but last week, they didn't say anything about welding glasses as an alternative to eclipse glasses.

Viewing with Protection -- Experts suggests that one widely available filter for safe solar viewing is welders glass of sufficiently high number.

The only ones that are safe for direct viewing of the Sun with your eyes are those of Shade 12 or higher.

These are much darker than the filters used for most kinds of welding. If you have an old welder's helmet around the house and are thinking of using it to view the Sun, make sure you know the filter's shade number.

If it's less than 12 (and it probably is), don't even think about using it to look at the Sun.

Many people find the Sun too bright even in a Shade 12 filter, and some find the Sun too dim in a Shade 14 filter — but Shade 13 filters are uncommon and can be hard to find. The AAS Reputable Vendors of Solar Filters & Viewers page(link is external) doesn't list any suppliers of welder's filters, only suppliers of special-purpose filters made for viewing the Sun.

@patbz, what @Verdana posted is correct. This is an excerpt about welding goggles from space.com. (emphasis added)

Welding goggles

Welders planning to observe the solar eclipse may or may not be in luck, as some welding filters will adequately protect your eyes from the sun. But, please, double-check to make sure that the goggles you intend to use are the right kind.

"There is a particular circumstance in which it's safe," Fienberg said. "We don't recommend it because it's too easy to get the wrong kind of welding filter." Only goggles made for electric arc welding can be used to observe the sun, and they must have a shade scale number of 12 or higher. Shade 13 is ideal for solar viewing, but that shade is typically not sold in stores, Fienberg added.

The eyes through which you see others may be the same as how they see you.

Worth repeating.
