Is the word vista the same in Brazilian and European Portuguese?

No.

While the spelling, grammar, and primary meanings (such as "scenery" or "view") are identical, there is a difference in typical usage regarding the sense of sight. In Brazilian Portuguese, "vista" is frequently used to refer to eyesight or the physical ability to see (e.g., "minha vista está cansada"). In Continental Portuguese, while "vista" can be used this way, the word "visão" is much more natural and common when discussing the physiological sense of sight.
