It is possible to cause blindness. There are many reasons of blindness.cataracts, glaucoma, high myopia, trachoma, keratitis, accident and so on.If you had a degree of big bang you might fail.
As for the treatment of the problem.when your eye damage,the probability of cure is tiny,your eyes could shrink with time flying,so you can do eye plastic surgery or install on fake eyeball to make your eyes look is the same as a normal person,what's more, your retinal detachment or fluid loss, you also have the little chance to cure.If your eye in a good condition,cured probability is higher than the former, you can go to do eye surgery to repair,usually pay attention to protect our eyes from harm as well.
Thank you for your reference,good luck!
