5mw green laser in my eye?

I just received one of the ebay 5mw greenlasers and i accidentally shined it in my eye this morning at around 7:20 am it is now close to 3 hours later and every time i blink i can see a black dot and when i close my other eye and try to read something it is blank where the dot is, is this temporary it was only on my eye for about a second and its the low 5 mw laser will this go away soon or will i have permanent eye damage?
5 hours still there :/
