Give me a shot of red-eye...

I had an eye examination today (which fortunately turns out to be good news, I don't have any immediate problems) which included a retinal examination, for which they had to give me drops to dilate my pupils.

It's started to wear off a bit, though I'm still seeing a halo around lights etc., but I never realised they could dilate this much:

I've put this on Wikimedia Commons if anyone has a use for it.
