Well, I've looked at the full noonday sun full on, eyes open, quite a number of
times in my life and still don't need a guide dog. Then again, it was only for a
few seconds, usually less than three before my eyes closed by reflex. For short
periods it's not the sure-fire way to instant eye damage it has been hyped up to be.
What *is* dangerous is looking through darkened glass or plastic that is
(unwittingly) transparent to IR. Then there is no indication of potential damage
until the burns start to appear.

Well, I've looked at the full noonday sun full on, eyes open, quite a number of
times in my life and still don't need a guide dog. Then again, it was only for a
few seconds, usually less than three before my eyes closed by reflex. For short
periods it's not the sure-fire way to instant eye damage it has been hyped up to be.
What *is* dangerous is looking through darkened glass or plastic that is
(unwittingly) transparent to IR. Then there is no indication of potential damage
until the burns start to appear.
