Thousands of counterfeit solar eclipse glasses may harm viewers' eyesight; ensure authenticity with three tests before use.

Thousands of counterfeit solar eclipse glasses may pose a risk to viewers' eyesight, according to Scientific American. To ensure the authenticity of your solar eclipse glasses, follow these three tests: 1) Wear the glasses indoors and look around; the lights should be the only visible source of light. 2) Outside, the surroundings should appear too dark to see distant objects. 3) Briefly check the sun through the glasses. If the sun appears as a bright, sharp-edged circle, the glasses are likely safe to use. Always check glasses' authenticity before using them and consider purchasing from reputable sources to avoid potential eye damage.
