when you look directly at the sky, you squint, you pupils contract and 
can't look at it straight for 8 minutes, anyway.

When there's an eclipse, and you'r elooking through dark sunglasses, 
floppies, DVDs, welding masks, etc, the lower level of ambient light and 
the apparent darkness of the sun through the aforementioned spectacles 
will not be enough to tell your brain to take evasive manoeuvres, so you 
actually will burn your eyes with more UV rays than you would if you 
were driving west at dusk, or skiing on a glacier in the Alps.
