When I look through a binacular,I feel I am looking through the left eye or the left side lens.Does it had a connection with right or left hand writers?Whats the science behind it?

Answer:
Ocular dominance, sometimes called eye preference or eyedness,[1] is the tendency to prefer visual input from one eye to the other.[2] It is somewhat analogous to the laterality of right- or left-handedness; however, the side of the dominant eye and the dominant hand do not always match.[3] This is because both hemispheres control both eyes, but each one takes charge of a different half of the field of vision, and therefore a different half of both retinas (See Optic Tract for more details). There is thus no direct analogy between "handedness" and "eyedness" as lateral phenomena.[4]
Approximately 70% of the population are right-eye dominant and 29% left-eye dominant.[1][5][6][7] Dominance does appear to change depending upon direction of gaze[2][8] due to image size changes on the retinas.[9] There also appears to be a higher prevalence of left-eye dominance in those with Williams–Beuren syndrome,[10] and possibly in migraine sufferers as well.[11] Eye dominance has been categorized as "weak" or "strong";[12] highly profound cases are sometimes caused by amblyopia or strabismus.
In those with anisometropic myopia (different amounts of nearsightedness between the two eyes), the dominant eye has typically been found to be the one with more myopia.[13][14] As far as regards subjects with normal binocular vision, the widespread notion that the individual's better-sighted eye would tend to be the dominant eye has been challenged as lacking empirical basis.[15]
Dominance can change and may switch between the eyes depending on the task and physical condition of the subject (i.e. fatigue).
Answer:
Just like we use one side of our body more than the other and have a dominant hand that we use for writing, most of us also have a dominant eye.
A dominant eye isn’t always about one having better vision, but rather one leading better than the other because of preference. Your dominant eye is the one that provides slightly more input to the visual cortex of your brain and relays information more accurately, such as the location of objects.
Research shows that eye dominance and handedness are associated, though not directly related. Someone who is right-handed is more likely to be right-eye dominant, but it is possibleto be right-handed and left-eye dominant.
Eye dominance can vary from person to person. One person may have strong degree of dominance in one eye, while another person may have an eye with a lesser difference in dominance from the other eye.
