Depth perception is the visual ability to perceive the world in three dimensions (3D) and the distance of an object.
Diplopia, commonly known as double vision, is the simultaneous perception of two images of a single object that may be displaced horizontally, vertically, diagonally (i.e., both vertically and horizontally), or rotationally in relation to each other.
Esophoria is an eye condition involving inward deviation of the eye, usually due to extra-ocular muscle imbalance.
Esotropia is a form of strabismus in which one or both eyes turns inward.
Exophoria is a form of heterophoria in which there is a tendency of the eyes to deviate outward.
Exotropia is a form of strabismus where the eyes are deviated outward.
The extraocular muscles are the six muscles that control movement of the eye and one muscle that controls eyelid elevation (levator palpebrae).
Eyes are organs of the visual system.
Eye movement includes the voluntary or involuntary movement of the eyes, helping in acquiring, fixating and tracking visual stimuli.
The field of view is the extent of the observable world that is seen at any given moment.
The fovea centralis is a small, central pit composed of closely packed cones in the eye.
A gun turret is a location from which weapons can be fired that affords protection, visibility, and some cone of fire.
Hering's law of equal innervation is used to explain the conjugacy of saccadic eye movement in stereoptic animals.
Hering's law of visual direction describes the perceived visual direction of a point relative to an observer.
In studies of binocular vision the horopter is the locus of points in space that have the same disparity as fixation.
In ophthalmology, horror fusionis is a condition in which the eyes have an unsteady deviation, with the extraocular muscles performing spasm-like movements that continuously shift the eyes away from the position in which they would be directed to the same point in space, giving rise to diplopia.
Hypertropia is a condition of misalignment of the eyes (strabismus), whereby the visual axis of one eye is higher than the fellow fixating eye.
Java is a general-purpose computer-programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible.
Latin (Latin: lingua latīna) is a classical language belonging to the Italic branch of the Indo-European languages.

In anatomy, the orbit is the cavity or socket of the skull in which the eye and its appendages are situated.
Orthophoria condition of binocular fixation in which the lines of vision meet at the object toward which they are directed, and considered as a normal condition of balance of the ocular muscles of the two eyes.
Orthoptics is a profession allied to eye care profession whose primary emphasis is the diagnosis and non-surgical management of strabismus (wandering eye), amblyopia (lazy eye) and eye movement disorders.
Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines.
