I have very limited vision with my right eye due to a retinal detachment may years ago. My vision is extremely blurred and distorted (a straight line doesn't appear straight). I cannot read the words on this screen from ~12 inches through my right eye. Fortunately, I am LH and left-eye dominant.
Even your limited vision is much better than nothing. While your right eye may not help much with seeing detail, it is still very useful for things such as depth perception.
I would keep working at it. Shoot with both eyes open to help with depth perception. Over time you will find that your shooting will improve as you adjust to your handicap.
