Why take the chance of permanently damaging your eyes by looking directly at the sun through some cheap filters that might not be safe?

Long before these "glasses" appeared on the market, newspapers and magazines would always publish instructions on making simple pinhole camera projects to view solar eclipses. You can still find them online with a search.

I recall one partial eclipse when I was about 11 years old while we were swimming at a lake. My parents had warned us not to look at the sun, but I saw some adults holding up their hands and peeking at the eclipse through the narrow gaps in their fingers. There is no doubt that they damaged their retinas. I don't recall, but I hope that none of the kids at the beach that day copied them.
