"Staying Safe During the Solar Eclipse: Tips for Watching and Photographing Without Risk"

Counterfeit solar eclipse glasses from China are being sold in the US, posing a risk of "temporarily impaired vision" or "permanent blindness." The suspect frames impersonate legitimate ones and are no darker than regular sunglasses. Legitimate solar glasses should be at least 1,000 times darker than regular sunglasses and have an International Organization for Standardization (ISO) certification. The American Astronomical Society advises caution and provides a list of legitimate vendors, while New York State offers free solar eclipse glasses at city libraries and transit routes.
