On my way to work the other night, it started to get blurry in the eye that is usually effected and then everything looked yellow. It lasted about 15 seconds and was gone.
About a half hour later I started to get a headache, it got up to about a kip 3 but I aborted it with sumatriptan nasal spray.
Kinda strange and scary with everything turning yellow especially while i was driving.

Never had an experience like such.  My blurry vision comes from applying to much pressure to my eye during a bout. 

Yeah, it's not in my experience either. The only blurred vision I get is from the tearing. It's worth asking a doc about if it happens again. blessings. lance
