Dextrocular is a term that refers to having a dominant use of the right eye. Its spelling can be explained using the International Phonetic Alphabet (IPA), which uses symbols to represent the sounds of speech. The first syllable, "dex," is pronounced with a "d" sound, followed by the schwa sound "ə." The second syllable, "tro," is pronounced with a "t" and a long "o" sound represented by the symbol "oʊ." The final syllable, "cu-lar," is pronounced with a "kyu" sound, followed by "lər." Together, the word is pronounced as "dek-strō-kyu-lər."
Dextrocular is an adjective used to describe an individual who primarily or predominantly uses their right eye for visual activities or exhibits a stronger preference for their right eye over their left eye. The term is derived from the Latin words "dexter," meaning "right," and "oculus," meaning "eye."
In terms of ocular dominance, dextrocular individuals demonstrate a natural inclination towards using their right eye as their dominant eye for activities such as reading, writing, driving, or any task that requires precise vision or depth perception. This preference for the right eye does not imply that they are unable to use their left eye effectively, but rather that they tend to rely more on their right eye for optimal visual performance.
Dextrocularity is determined by the ocular dominance established during the developmental stages of an individual's visual system. It is commonly observed that right-handed individuals tend to have a right-dominant ocular preference, resulting in their classification as dextrocular. Conversely, left-handed individuals may exhibit a more equal or even a left-dominant ocular preference.
Assessing an individual's ocular dominance, including dextrocularity, is important in various fields such as optometry, ophthalmology, and vision therapy. Understanding an individual's ocular dominance can aid in the diagnosis and treatment of visual conditions and guide the implementation of appropriate visual correction strategies.
Righteyed; noting one who uses the right eye by preference in monocular work, such as the use of the microscope.

The word "dextrocular" is a combination of two roots: "dextro-" and "-ocular".
The prefix "dextro-" comes from Latin and means "right" or "on the right-hand side". It is derived from the Latin word "dexter", which means "right" or "skillful". This prefix is commonly used in scientific and medical terms to indicate something that has a rightward orientation or rotation.
The suffix "-ocular" is derived from the Latin word "oculus", which means "eye". It is widely used in English to refer to anything related to the eyes or vision. For example, terms like "binocular" (related to both eyes) and "monocular" (related to one eye) are derived from this suffix.
