While lab tests are the best way to determine whether glasses meet the ISO standard, Fienberg says there is a three-part test people can do at home if they’re concerned their eclipse viewers aren’t up to the task.
First, put your glasses on indoors and look around. The only things you should be able to see are very bright lights, such as a halogen bulb or a smartphone flashlight.
Then, if the glasses pass the indoor test, bring them outside—but don’t look at the sun just yet. Look around: it should be too dark to see distant hills, trees or even the ground.
If that second test is passed, keep the glasses on and quickly glance at the sun. You should comfortably see a bright, sharp-edged round disk. If your glasses pass all three tests, they are probably safe to wear. Still, Fienberg points out that it’s best to use them for only a few seconds every minute or so during the eclipse…
