Many who arrive on our site are sent there from the American Astronomical Society's (AAS) website. Specifically, the AAS's site listing vendors of eclipse glasses and solar viewers. Eclipse Glasses USA is an approved vendor of eclipse glasses. We achieved this status by confirming with the AAS Senior Advisor to the Executive Officer that our products are lab tested in the US and certified ISO compliant. Only vendors that can certify their products' ISO compliant status are able to be listed on AAS's website.
So when you see AAS approved, you can rest easy knowing your eclipse glasses are the safest on the market.
