monokulært

Monokulärt is an adjective used to describe things that relate to or involve only one eye, or vision through one eye. In ophthalmology and optometry, monocular vision refers to the visual function of a single eye, which can occur when the other eye is impaired or suppressed. Binocular vision, which requires two functioning eyes, supports stereoscopic depth perception; this is reduced or absent in monocular viewing.

Monocular vision affects depth perception, as most depth cues rely on input from both eyes. People with monocular vision often rely on monocular cues such as relative size, occlusion, perspective, shading, and motion parallax to gauge distance and spatial relations. Compensation strategies may include increased head movements and adjusted reliance on these cues.

Monocular devices are optical instruments designed for use with one eye. A monocular, or monoculär optiskt instrument, is a small, portable telescope that provides magnification for distant objects while preserving peripheral vision on the other side. Monoculars are commonly used in activities such as birdwatching, hiking, sports viewing, or by individuals with limited vision in one eye to aid distance viewing.

In medical and research contexts, the term also appears in discussions of visual disorders, rehabilitation, and the study of how the brain processes visual information from a single eye. The term may be used similarly in other languages to distinguish one-eyed (monocular) from two-eyed (binocular) visual or functional scenarios.
