The term "eye-bulb" generally refers to the eyeball, but there are other synonyms you can use when talking about this essential organ of the body. Some of the common synonyms of "eye-bulb" include "ocular globe," "orb," "eyeball," and "scleral shell." While all of these terms are used to refer to the ball-shaped part of the eye, they may be used in different contexts depending on the conversation or subject matter. For instance, medical professionals are most likely to use the term "ocular globe" to describe the eyeball, while laypersons would generally prefer the more common term "eyeball".
