Patterns and grids in vision

[Kellen]

Had a brand new symptom show up the other night. Was hanging on my friends porch with some candles lit when out of nowhere I got all these weird revolving patters and grids in my right eyes field of vision. I don't know if the candle light played some roll but it was really weird and it took over about 1/4 th my vision. It was like triangles and grids that swirled round And stretched I can't really describe it any other way. All different colours but mostly red/orange and purple. It last about 10 mins wtf has anyone had this? I can't believe Im still getting new symptoms like this after all these years I hope it doesn't happen again it was freaky
