I am in the USA and in most States here, if you have normal vision (20/20) with or without glasses, as well as in normal visual field in your one remaining eye, you can normally obtain a drivers license.
Being blind in one eye is normally not a reason to be denied a drivers license in the USA.
Now. In Ireland?
I really don't know for sure :(
But...you could call the place that issues drivers licenses and they will be able to answer your question.
You might want to have a copy of your ophthalmologists report in-hand when you contact them so you can answer any questions they may have about your remaining vision.
But I bet you can get a drivers license from what you have told me here today.
Does this make sense to you?
It's safe for you to press the positive feedback button now if you so desire. And, never fear, even after you press that button I'll still be right here to continue helping you, but, as I do work for tips, I want to make sure you are happy before rating me.
