I've been seeing lights every once and a while but didn't think much of it. Its always in the lower part of my vision, on the left of my left eye, right of my right. It sort of looks like fire, going from the bottom up a bit. I think it happens more in my left eye.

The reason I'm posting this is because my eyes are starting to hurt. I was just playing guitar on Rock Band, and since I went up a level in difficulty my eyes started bothering me. Mostly my left one, in the top right corner. Which is the area where I would be seeing the lights, due to the image being flipped after going through the lens.

I don't know too much about eyes, and this could be a problem unrelated to them, maybe neurological, I haven't a clue. I'm just wondering if someone out there might know whats up.
