Pronunciation: [hˈɒɹɒptə] (IPA)

Horopter (/həˈrɒptər/) is a term used in ophthalmology and optics to describe the imaginary line that connects points in space which are seen by both eyes and appear to be single. The word is spelled with "h", "o", "r", "o", "p", "t", "e", and "r". The stress falls on the second syllable "ropt", and is pronounced /həˈrɒptər/. The "h" is pronounced as "ha", while the "o" is pronounced as "oh". The "t" is pronounced as "ti" and the "e" is pronounced as "eh".

HOROPTER Meaning and Definition

1. The Horopter is a term widely used in the field of vision sciences to describe an imaginary surface or line where the binocular visual axes intersect. It is primarily related to the perception of depth and the coordination of visual information from both eyes. The horopter is essentially the location in space where objects have no disparity, meaning that their images fall on corresponding points of the retinas in both eyes.

   In simpler terms, the horopter can be thought of as the apparent boundary or locus of points in space that appear to be at the same distance, resulting in a single, fused image. It serves as the reference plane for the coordination of binocular vision, allowing the brain to integrate the slightly different views presented by the two eyes into a coherent visual perception of depth and three-dimensionality. Objects located on the horopter will be perceived as being at the same distance from the observer.

   The horopter is not a fixed or pre-defined surface, but rather a dynamic concept that can vary based on several factors, including the position and orientation of the eyes, the distance of objects, and the vergence angle (the angle at which the eyes converge or diverge to fixate on a target). Additionally, deviations from the horopter can provide important cues for the perception of depth, such as when objects appear closer or farther away from the reference plane.

2. The sum of all the points in the binocular field of vision, in any fixed position of the eyes, rays from which fall upon corresponding points in the two retinas, the image therefore appearing single. The horopter may be a straight line or a plane, a curved line or a curved surface.
