With welders goggles to watch the solar eclipse is harmful to the eyes?
There are special solar eclipse observation glasses, the price is very cheap, 5-10 pieces of a pair, but in many places did not sell, you know, these glasses are usually useless. Don't think sunglasses are OK, no..
Who says only goggles sunglasses, sunglasses only take ordinary silver iodide coated on the glass.
Welding welders can see the glass.
