    Im going to get another pair of glasses to use one of the lenses over my camera. That way I'll hopefully get good pics of the eclipse. 
    A pair for Alli?

    Will polarized lenses be safe enough?

    No. You need the ones specially designed for an eclipse. And there are precious few available right now.

    Alli won't be eclipsing. He has a head injury from the accident. He wasn't buckled in. No I wasn't driving.

    You never really had to begin with.


    Sometimes it's not the song that makes you emotional it's the people and things that come to your mind when you hear it.

    I trust the driver is dead and buried for such negligence.

    Or have you gone soft?

    Depends on % of totality.  Essentially, no, not at all.
    At 100 there's no problem with naked eye.  Anything below that and there's danger.  
    The problem is, you can get solar retinopathy without discomfort because there's is a slightly delayed inflammatory response that actually causes the retinopathy.  So maybe you look at a 90% eclipsed sun with sunglasses for 5 minutes and you don't feel bad, and then later it swells and hurts and you have permanent, irreversible vision loss.

    In 4th grade (1984?) the last solar eclipse I really remember.  it was around lunch time and everyone went outside to see it, it was pretty cool.  although don't remember wearing glasses or anything, maybe we had the paper plates with holes in them.

    I remember that Dave. I was in elementary school and we looked down into boxes.

    It's already crazy here in Oregon. Gas stations are running out of gas and traffic is already backed up for miles.

    I'm only about 40 miles from totality but we're making a trip over the cascades. Leaving in the morning probably really early to try and avoid some of the traffic. Although we'll be out for 3 days and had plans for some other hiking it seems we may be stuck at our campground.

    Hell no.  

    To give you an idea, you will need to wear what a welder wears.  Particularly a Tig welder, so a #13 darkness lens.

    Sunglasses at best are a #3.  Cutting goggles for when you use a torch are #5.  Normal welding lenses are #9-11.

    I'm here in Myrtle Beach, will have a very good look at this.
    I plan on wearing a pair of swimming goggles and the granny/Stevie Wonder shades. Should be good to go.
    And so you see, I have come to doubt
    All that I once held as true
    I stand alone without beliefs
    The only truth I know is you.

    Hahaha!  Hell no is right. You'll be staring directly at the sun.  I have glasses from the planetarium in Chicago, they are so dark and thick I can't see anything through them except the sun.

    Yeah they are so dark all things except the sun are blocked out. I  read welders goggles should be a 14 to be safe. Hope everyone has a safe and inspiring view when the sun is eclipsed by the mooonnn.

    I ordered a record this morning and got a nice note back saying, "Will ship Monday or Tuesday if possible- depends on the eclipse traffic."  :lol:

    You can check your eclipse percentage and see a nice graphic of how it will look here:

    My husband laughed at me for that too :blush:

    But the odd change in timing of light could mess with them in ways.  I heard that birds and other animals might revert to nocturnal behaviors.
