Wires may be solid (simple drawn wires), or cored (composites formed from a metal sheath with a powdered flux or metal filling). To find the best solar eclipse glasses, we followed advice from authorities in astronomy and well guidance from NASA's eclipse safety webpage and Senior Advisor to the Executive Officer and Project Manager for the American Astronomical Society Richard Tresch Fienberg, PhD. Denise Hill, heliophysics communications and outreach lead at NASA, has good news for you: solar viewing glasses are constructed to work with existing frames.

The astronomical spectacle is what happens when the moon passes between the sun and Earth while it’s at the farthest point from Earth, causing the moon to partially block the sun and create a “ring of fire” effect in the sky. JRA Welding has been involved in fabrication work for multiple downtown area businesses, including handrails, signs, and other architectural details. They both use metal-coated black polymer film manufactured by Thousand Oaks Optical, and most of the resellers on our list get their glasses from either APO or RS—including some big retail chains such as Home Depot, Lowes, and Walmart. Weld made by filling a hole in one component of a workpiece with filler metal so as to join it to the surface of an overlapping component exposed through the hole (the hole can be circular or oval).

For droplet or spray transfer, a much higher voltage is necessary to ensure that the wire does not make contact i.These are pricier than other eclipse glasses on our list, but they’re also sturdier than other plastic picks, plus they offer some side shading so they aid in protecting your peripheral vision as well. This eclipse viewer’s sturdy build and value-forward bundle includes one pair of plastic Eclipse Shades, an attachable elastic cord, a carry case, plus two bonus paper solar viewing glasses.
