Abstract
Individuals in most cases have preference for a particular eye especially when they are required to use an eye rather than both, such as when viewing a monocular microscope, when taking a shot at a target with a high level of precision. A number of factors have been given for such variations among individuals. This factor is however peculiar to such individuals and could be used as a means of identity among other possible applications. Sex- male or female, handedness- left or right as well as dermatoglyphic patterns of the fingers are other popular means of identifying individuals. This research assessed monocular eye preference and its possible relationship with sex and handedness among 120 subjects who have not been diagnosed of any visual impairment and without any sign and symptom of such. The individuals' choice of monocular vision was confirmed through a test involving subjects using a single eye to view an object demonstrated on the microscope. Thumb prints were also collected to evaluate possible relationship between selected parameters. Sex was either male or female; handedness included left, right or ambidextrous. Data were subject to analysis. Results show that about half of the subjects naturally use the right eye for monocular vision; about nineteen out of every twenty were right handed, about three out of a hundred were ambidextrous, while about half combine both right hand and right eye. Interestingly, left handedness was not observed in the study group.
