In assessing the classifications of fixation, it's important to recognize the established categories that help describe how the eyes hold their gaze. Central fixation refers to the ability to focus on a single point within the fovea. Steady fixation indicates the ability to maintain visual focus without movement. Maintained fixation reflects the capacity to hold a position steadily for an extended period.

The term "primary" doesn’t typically represent a recognized category of fixation in standard ocular motility or vision science. Therefore, identifying "primary" as not being a classification highlights a clear understanding of the language commonly used to describe how the eyes stabilize and direct gaze. This distinction emphasizes the specificity of fixation categories and their relevance in clinical practice, making the answer correct based on established definitions in ophthalmology.
