basically, go outside and look at the sun right now. that's what it'll look like for you if you're not in 100% totality. the glare will mostly outshine the moon and you'll only be able to glance for like a second before you need to turn away.
i'm in the 90% range. got some glasses, really excited. mostly excited to see it dark in the day time, gonna be interesting.

oh also, if you don't have glasses, go check at the animal shelters in your area.
the weather channel said some might be giving them away for pets for some reason.
