@crgildart While not engineered for the sun and thus not recommended, arc welding lenses offer protection. Gas welder glasses do not offer enough protection. Eclipse glasses will be best (as long as they aren't fakes - unfortunately there are some fake eclipse glasses so be aware).

The ones I bought are listed as dual argon "arc welding glasses". Perhaps we could wear BOTH those and the sketchy Amazon ones doubled up hahaha. Pretty sure we will feel discomfort and look away for a bit if the sun is damaging our eye more than it does at 10K on a bluebird day without any sun glasses at all..
