The wiki for oculama states that it is a form of symbol-shaped eyes. It also states,

There should be nothing that can be identified as a sclera, or iris for this tag to apply. For example, a heart symbol replacing the iris of a character should be tagged heart_eyes, not heart_oculama.

However, the wiki for symbol-shaped eyes lists the *_eyes set of tags as examples of symbol-shaped eyes, not the *_oculama set of tags. This directly contradicts the description for oculama.

Which of these definitions is correct?
