"Sinistrocular" is a rare term that refers to the ability to see more clearly with the left eye than the right eye. There are a number of synonyms that can be used to describe this condition, such as "left-eye dominant," "leftward bias," or "eye-dominance anomaly." Another term that is sometimes used to describe this condition is "ocular suppression," which refers to the way in which the brain suppresses the signals coming from the weaker or less dominant eye, in order to help maintain clear vision. While "sinistrocular" may not be a commonly used term, it is useful to have alternatives in order to describe the phenomenon more clearly.
