Dominant eye - (oculus Dominus)
The eye dominates the mind of the viewer, not the person looking at it. It is important to note that today the dominant eye is a term from ophthalmology! How the viewer sees depends on the position of his eye. The optic nerve transmits visual information to the brain in what is called a sequential order from one eye to the other. In this case, the right eye sends visual signals first, then the left, and vice versa. At the same time, our brain processes information that is seen first by the right eye, and if we see better with the left, then the sequence is different. Under normal conditions, both eyes work simultaneously, but sometimes one may work "better" than the other. The “leading” eye suppresses the work of the partner, sending information directly to the corresponding pole of the brain. Controlled, it can also change it, enhancing or dampening the functions of the second eye, which is not under our control. In this way the eye can become dominant. The two eyes can function together or as two different eye organs. This is because the brain can control and suppress the dominant side of the eye, while the other side can dominate. According to M. Adasson, in adult men the dominant eye is more often the left one and only in 5–14% the right one. This statistics does not change significantly until old age, also manifesting itself in patients with sclerosis: in patients with manifestations of sclerosis for at least 6 years, a slowdown in blood circulation was noted in right-handers. But most often, the vision of both eyes is equally (35–46%) or, conversely, equally poor (17–25%). Less common is unilateral visual impairment, in which the eye never becomes dominant (20–23%). The theory of eye dominance was confirmed empirically through clinical studies by P.V. Terentyeva and A.A. Troshina. Comparing the results, the researchers found similar characteristics of the oculomotor function of the fellow eyes of different patients. It is very interesting that ophthalmologists even determine the degree of dominance using fundus data. At the very least, there is a probability of becoming a “dominant eye” for the left eye and a high probability of acquiring this pathological predisposition for the right one. This is considered a normal outcome in about a quarter of the population.
