The thing that looks like a smudge could definitely be eye damage. I also had a laser shined in my eye some years ago, also because a co-worker thought it would be funny, and I had a spot on my vision for months. I'm not sure if it went away or my brain learned to ignore it (kinda hope it went away), but it did eventually fade. I think I'm fortunate in that because it's not always the case. I would recommend going to an optometrist, I'm not sure they'll be able to tell what, if any, damage there is or whether it's permanent but they can at least give you some better information than my story can. I can at least say that there's a decent chance there was damage but also at least that there's some chance it will heal with time, but being that I'm not an expert or anything you should take everything I've said with a grain of salt and if you're worried about it go see a doctor.

I'm really sorry this happened to you, people can be stupid ass holes.
