szemközti

Szemközti is a Hungarian adjective meaning “between the eyes” or “interocular.” It describes something that is located between the two eyes or relates to the space separating them. The word is formed from szem (eye) and közti (between) and is used in medical, optical, and technical contexts.

In ophthalmology and optometry, the phrase szemközti távolság refers to the interpupillary distance (IPD), which is the distance between the centers of the pupils. IPD is commonly measured in millimeters and is essential for properly fitting glasses, contact lenses prescriptions, and optical devices. Accurate szemközti measurements help ensure comfortable vision, proper alignment of lenses, and correct binocular viewing.

Beyond medicine, szemközti concepts appear in fields such as optics, photography, and virtual reality, where the spacing between the eyes affects stereo imaging, depth perception, and device ergonomics. For example, VR headsets and binoculars often require settings or adjustments based on eye distance to avoid eye strain and to optimize a three-dimensional viewing experience.

In English, the direct equivalent is interocular, though in Hungarian the standard form is szemközti. Related terms include interpupillary distance and pupillary distance, which are used in medical notes, optical design, and product specifications. See also interpupillary distance and interocular distance for cross-linguistic reference.
