The advantage of seeing with only one eye is that when it is good, you see well. If, on the other hand, you have two eyes and one of them is impaired, this affects your overall vision. So the good eye cannot correct or cancel out the defects of the corrupted eye. On the other hand, if you see with only one eye, you lose the depth of field that can only occur with two eyes, preferably healthy ones. Clear vision therefore imposes certain conditions. This is also true in a figurative sense. If we are biased in our view or no longer objective, this will automatically influence our view and thus our interpretation of what we see. This can be positive or negative. Therefore, it is good to critically question ourselves every now and then how our made opinions, judgements or evaluations come about and from which perspective and interpretation they originate. This check can prevent us from making wrong decisions.
I wish you an extraordinary day!
