###Human: Can eye sight lost due to rocket blowing up in eye be cured? ###Assistant: Hello. Thankfully only one eye was affected and I hope your other eye is intact and fully functional. Unfortunately, a dilated pupil that does not react to light in the affected eye means that it is no longer transmitting information to the brain and therefore is considered non functional. In most cases those changes are irreversible and the eye is no longer considered a functioning organ. But, hope dies last, and to cheer you up a bit, there are many ongoing clinical researches on the restoration of vision in blind eyes and mainly involve implanting a chip in the retina and connecting it to the brain and although the results are not what a patient would expect, nonetheless it helps the eye detect objects on a very primitive level. As I said earlier, thank God that only one eye was affected and you should take care of it by undergoing a yearly comprehensive eye exam. I wish you best of luck.
