There's a phenomenon here called the "Seattle Squint".
It's what happens to people here in the summer when the clouds break, the sun comes out, and people haven't had time yet to buy new sunglasses. :-)
One of the Album Rock FM stations used to do this phony PSA commercial on sunny days that opened with this deep God-like voice bellowing out over loudspeakers:
"Citizens... of... Seattle...! Do not... be... alarmed! That bright yellow object in the sky is called 'The Sun'... It will not harm you... Please... do not be alarmed!"
:-)
Ha! Yeah, in Germany when we had a sunny day, at least one person would come into work and say "Does anyone know what that big bright thing in the sky is all about?"
The climate really did a number on folks from exceptionally sunny areas, seriesly. Had a lot of folks end up majorly depressed. It took me awhile to adjust, too. But eventually, I realized it meant for once I could actually go on bike rides and stuff and not worry about having trouble seeing or that horrible flashing effect of light through branches.
