When glaucoma has already caused vision loss, further vision loss may occur even after the pressure in the eye is lowered to the normal range with medicine. Talk to your doctor about the goals of treatment, how long the medicine will be tried, and the possible side effects.
Game character. Yoda is a playable character in Lego Star Wars: The Video Game, Lego Star Wars II: The Original Trilogy, Lego Star Wars: The Complete Saga and LEGO Star Wars III: The Clone Wars. In all four he wields a green lightsaber and is a Jedi character, so can use The Force. In the latter he can also throw his lightsaber.
What language does Yoda speak? The answer to this is surprisingly clear: It's English (duh). In all five of the movies he's in, he speaks only English. This is not to say that he doesn't speak any other language, but we actually don't have any evidence he does. He could be a monolingual speaker of the kind of English he speaks. There are dialects of English that are more different from the Queen's English than Yoda's is.
