Thank you Mark. Now I just pray the sun will shine during my totality  in the afternoon. There is a 50/50 chance of clouds right now but looking better by the hour that the sun will break through.

Some people say to keep glasses on during totality so just to be safe I will do that but am very thankful for your response.

You will not see a thing (not one thing) with your eclipse glasses on during totality. You will have a hard time seeing anything with your sunglasses on during totality. It gets very, very dark. The Sun's corona is a lot less brighter than is a full moon, and that is all that will be providing light.

The moon completely blocks the Sun during totality.  So not only is it safe to view without the glasses, you won't see anything at all with the glasses on.

Please link to the article.  The answer given on your previous question is correct.  You wear the glasses *until* totality and replace them as soon as totality ends.  Unless you can provide the source of any other information this is a straight duplicate.

That eye doctor did not know what they were talking about. You will not see a thing through those eclipse glasses during the 30 seconds, maybe the last minute before totality. It is not yet safe to look at the Sun. Have a very good eclipse calculator & an accurate watch or clock. A cellphone that receives GPS input is an accurate clock. Input your precise location (lat, long, altitude) into the calculator and set an alarm for five to ten seconds prior to totality. Set this up hours in advance. Take the eclipse glasses off when they become useless. Then wait until the alarm goes off.

The risk is that if you take your glasses off too soon, or if you're staring at the Sun at the moment it reappears, you might suffer eye damage. The tiny fraction of the Sun that's visible isn't bright enough to trigger your protective blink reflex, but it's still bright enough to cause damage.

During the core of totality, looking at the eclipse with the naked eye is safe.
