Could my eyes be damaged?

I looked out the window and accidentally looked at the sun for a very short moment and looked away as it started hurting immideately, so I didn't look at it even a second. Now there are some of these you know these lines and spots which are first green and then purple which come from looking at some light. But these lines and spots have been on my eyes longer than usual, about 5 minutes when usually they are about 2-3, is this just because the sun is brighter than other light sources, and could this have damaged my eyes? Should I be worried? Do you have some own experience? Thanks!
