I have occular migraines which scared the crud out me, but never color blindness. Mine are a tunneling of vision, sometimes the light show as Beth called it. I have been fortunate thus far not to have my occular migraines be followed by my real migraines. I had a lot of tests to rule out blood pressure and heart issues before being diagnosed. Good luck Limewave, for me vision issues scare me more than anything else.
