Go to the range and shoot and see what your ethical capabilities are. I feel like this is a question only you can answer for yourself.I agree, I don't know how the scope will help unless someone points out the animal to you.
How about getting a special prescription for hunting purposes? For instance, I'm far sighted, and I'm completely fine with a scope. Therefore, I don't wear glasses for hunting with a scope. Your eye doctor could possibly do something like that for you.
