Why is it that on the few times i've tried Viagra, i get 'blue' vision?

Question

I'm a young guy that has only taken viagra recreationally. a couple of times...just for fun w/the gf. my heart is healthy. i had a few drinks while takingit as well.

why did my vision appear blue? i've seen one or two references to this in the media, but don't recall the explanation. it was strange - i saw blue 'trailers', and my vision seemed very clear. i could see blue when i closed my eyes as well.

Call your doctor's nurse. If she doesn't know, she'll ask the doctor and get back to you.  I'm pretty sure I've read that it's nothing to worry about.  But, still, it's better to be safe..... ;)

This is one of the well know side effect of sidenafil citrate dear. It's the reason why pilots are advised not to take viagra less then 8 hours before flying...
