Don’t get scammed — Safe, NASA-approved eclipse glasses and where to snag a pair

 
 
 

This story has been updated with a newer list of approved manufacturers from NASA and the American Astronomical Society. Note that many of these companies have run out of stock ahead of the Aug. 21 eclipse.

Without proper eclipse glasses, a glance at the sun during the total solar eclipse this August could lead to potentially dangerous injuries.

But with all the hype surrounding the Great American Eclipse on Aug. 21, a quick Google search for eclipse glasses shows a number of retailers selling counterfeit eclipse eyewear.

NASA initially recommended four certified manufacturers but has added to that list of certified eclipse glasses and handheld viewers that meet the ISO 12312-2 international standard for eye and face protection.

 

American Astronomical Society- and NASA-approved eclipse glasses and handheld viewers:

NASA also warns against using homemade filters, sunglasses (no matter how dark) or unfiltered cameras, telescopes, binoculars or other unfiltered devices when looking at a partially-eclipsed or un-eclipsed sun.

Additionally, if the glasses are older than three years or have scratched/wrinkled lenses, they should not be used.

You can also opt to use a pinhole projector instead of eclipse glasses. From NASA:

An alternative method for safe viewing of the partially-eclipsed Sun is with a pinhole projector. With this method, sunlight streams through a small hole – such as a pencil hole in a piece of paper, or even the space between your fingers – onto a makeshift screen, such as a piece of paper or the ground. It’s important to only watch the screen, not the Sun. Never look at the Sun through the pinhole -- it is not safe.
