  • “There’s no way to tell just by looking at them whether eclipse glasses are genuinely safe,” Fienberg said, “but it’s easy to tell if they are not safe.”

    Try on the glasses indoors first. Nothing should be visible through the lenses, and even the brightest lights should only appear very faintly. If furnishings or wall decor are visible through the lenses, these glasses aren’t safe to view the sun.

    But if the glasses pass the indoor test, the AAS recommends putting them on outside during a sunny day and looking around. Again, nothing should be visible through the lenses, unless the sun is reflecting off an exceptionally shiny surface, and even then the light will appear faint if the glasses are safe.

    If the glasses pass that second test, try looking at the sun through them for less than a second. If the glasses are safe, the sun will appear comfortably bright and likely white, yellow, orange or bluish white.
