Does anyone know where they can be bought on stx?
Partial:
Saw an ad on Consortium last week that one of the eye care places was giving the glasses out for free while supplies lasted. Can't remember which.
Apple swears that it won't destroy their camera lenses without filters (although other sites disagree). So we're going hedge our bets and look using old iPhone.

Do not view directly or thru cell phones, multiple layers of sunglasses, etc.
You can permanently damage your eyesight.
Don't allow your pets to do so either or it will damage theirs as well.

Neither of these articles discusses cell phones. You are not looking through the optical device on a smart phone. You risk (if you don't believe Apple, in consultation with an astrophotographer) damaging your phone's camera sensor. But not your eyes. Not going to see much until it goes near peak anyway. Not my first decent eclipse, so not interested in following from start to finish. Will mostly be checking in on the total with live-stream.
As for my dog, don't worry. I've been keeping eclipse news hype away from her so she won't know she'll be missing a once in her lifetime experience. She'll hate me afterwards. But she'll get over it.
Hey, it's your vision.
Have at it.
There's nothing magical about eclipses over regular sun except for the fact that they reduce or eliminate the pain of staring at the sun, don't cause as much blinking and squinting, and your pupils are dilated more. So people fascinated by the phenomena have no physical cues they are being harmed. Looking through optical lenses (binoculars, SLR cameras, telescopes, etc) without a filter magnifies the effect and transfers the rays to your eyes. The image on the smart phone camera is not a transmission of the harmful rays that cause eye damage, but an interpretation of the light that enters the lens. I've taken many afternoon photos that include the sun. My eyes are fine and I haven't fried any sensors yet.
Simple as that. IFLS . 😎
Came across this:

Can I take a photo of the eclipse with my phone or camera?
No – this is particularly dangerous because your camera or phone will actually magnify the sun’s rays. It will be harmful to the device as well as your eyes. Think of how when you were a kid, you may have used a magnifying glass to generate a flame using the sun’s rays. If you wish to take a photo, you must purchase an adaptor for your lens – a filter that will prevent the censor from being burned. You can find these filters at places like: Best Buy, B&H, and Gear Patrol.

Ah, sigh.
I already said some say you risk damaging the camera. That's why I'm using an old phone. However, that site's response is poorly written and is misleading by lumping effects of both types of cameras together.
"NASA says if you’re using an iPhone or Android smart phone camera lens you should not need any added camera filter. Experts say the lenses on your smart phones are generally very small and do not admit enough light on auto focus.
So, your picture will actually come out over exposed and washed out but your phone camera should not be harmed."
Plenty more citations where that came from.

There is no comparison between a magnifying glass and a digital camera/display. A magnifying glass doesn't filter anything. An old analog camera view finder may not filter anything either and I wouldn't look through that at the sun.
A digital camera takes all the light frequencies, converts to ones and zeros, and then converts back again to put on the display. The nasty light frequencies that you don't need to see isn't converted because there is no need/value. Now whether or not the direct sun rays may damage the camera is another matter.
Helpful link, ya just type in your zip code and it tells you the % eclipse, by time of day for your area and when it's expected to peak
question.
if one can look into the sun on a regular day, why is the eclipse different.?
Well, you can't do that safely. And usually when you look at full sun, you aren't looking directly into it for a significant length of time (we're talking a number of seconds, here), which reduces the damage risk by not focusing the full rays to one spot in the back of your eye. But I splained why it's more of a danger with an eclipse already above:
"There's nothing magical about eclipses over regular sun except for the fact that they reduce or eliminate the pain of staring at the sun, don't cause as much blinking and squinting, and your pupils are dilated more. So people fascinated by the phenomena have no physical cues they are being harmed".
It's like saying, "But there were clouds, so why did I get a sunburn?" You didn't feel the direct heat as much, even though the rays were there.
Welding glasses have to be at least shade 13 or 14:
welding glasses for solar viewing
If you happen to have welding glasses on hand, you could use those.
