It's not too late to fix, but don't wait too long.
Can I eventually go blind in that eye if not treated? If so, is there surgery to correct it. I'm scared because I dint know if its to late to correct.
You need to be evaluated for either a retina or orbit problem. Go to a medical doctor who specializes in eye disease (ophthalmologist). If you are seeing "shadows" in your vision then this is a retina detachment until proven otherwise and you should seek care soon. If it is "double" vision, then it may be from a previously broken bone in your eye socket from the assault you sustained for which I'm deeply sorry.
