I once had a blindspot after a direct hit of 30mW or so. It was very small and there was only one though, so your situation sounds more serious. But in my case, the blindspot persisted for several weeks but eventually it did go away. Or my brain started correcting for it. Either way, I don't see it anymore, so there is some hope for you.
I've heard that if the blindspot(s) are kinda fuzzy and gray-ish, they might eventually go away, but if they are pure black and inactive they are likely permanent. I don't know if this is true though. You should definitely go see an eye doctor.
Also,you people that are just telling him he is stupid are not helping whatsoever. What's done is done.
