Eye protection for the Eclipse:
The eclipse glasses must say ISO 12312-2. If they have an incomplete or absent address, be suspicious.
Check the AAS solar eclipse website for vetted manufacturers/vendors (https://eclipse.aas.org/eye-safety/viewers-filters).
For true eclipse glasses, you should be able to see almost nothing indoors and outdoors. You should only be able to see something through them when you take a brief glance at the sun, at which time you'll see only the sun through the glasses. This doesn't guarantee that your glasses are fully protective, but these steps will at least eliminate some of the fakes.
Also, if you like the pinhole projection method, do NOT look at the sun through the pinhole. Let the eclipse shine down through the pinhole and look down at the shadow that it casts.

With the April 8th North American total solar eclipse just over two weeks away, potentially unsafe eclipse glasses are polluting the marketplace. Buyer beware!
