I was driving to a meeting and had just a very small slight headache that appeared to be going away, when gradually over the course of 10 minutes or so I noticed in the right side of my sight, in my peripheral vision I was noticing a weird wavy like distortion kinda like a film of water was around the outside of my eye that got worse and worse till it almost took over the entire sight in my right eye but then suddenly went away shortly after 15 minutes after it started. I don't think it was just my right eye because closing it and it appeared in the right side of my left eye and I could still see the distortion with my eyes closed. Later that day I felt fine, no headache or anything. There was no discoloration in my eyes, they weren't wobbling or drooping and they appeared fine. It kinda weirded me out and just wondering if this was just some precursor to a bad headache or migraine or something that I need to talk to my doctor about.
