Feather Loss Around Eye (teary Eye) And Little On Wing(what Is It?)

Hi guys, im new here so not totally sure how this site works, but Ive been having a problem with my budgie "Prinny". The little guy has a weeping eye and feather loss around ever since I saved him, but he's gradually lost feathers on his wing (where you can see) and more on his eye. He looks and behaves normal and loud ? droppings dont look lime green or too watery... Wondering if anyone can diagnose the problem and give me tips to help him. Please
