There is a book, out of print, you can buy on ebay or Google called "A Singular View" the art of seeing with one eye. It would be worth purchasing and reading.
As I said in my post I can't tell but this is a general guideline. If an eye is totally blind and does not have a tumor in it an enucleation is not done unless the eye is painful or terribly disfigured and a scleral shell cosmetic eye cannot be fit over the blind eye. At some point in the future you might be helped if there is still an eye or a "long" optic nerve.
Yes, get a second and third opinion. If the eye is not painful it might be possible to leave it. There is much work being done on artificial eyes with one called Argus 2 now in use for some cases (yours would not be a good candidate. Some day it might be possible to salvage some vision. A cosmetic shell can usually be fitted over the damaged eye to give it a normal appearance. Only if the 2nd and 3rd opinions recommend removal would it likely be the best course.
ALSO don't forget to take super good care of your remaining eye. Protecting from injury, disease, lead a healthy lifestyle, don't smoke, have regular eye exams regular physical exams and you should probably wear protective glasses all times even if your good eye not need glasses. If you do anything like mow yard you need industrial type protective eye shields
