What kind of glasses can I wear for the eclipse?
When it comes to safely viewing the eclipse, it’s recommended that you wear a pair of solar viewers from a vendor included on the American Astronomical Society’s (AAS) list of reputable manufacturers. Glasses from this list should also contain an International Organization for Standardization (ISO) number, like ISO 12312-2 or ISO 12312-2:2015.
If you already have a pair of eclipse glasses but you’re unsure of where they came from, you can always test them by taking them into a dark room and wearing them while looking at a lamp. If you can see the glow of the bulb, the glasses aren’t dark enough to be used for the eclipse.
