Summary Because there is no nerve in the retinal wall entering the ganglion, everyone has a blind spot in the field of view. Our brain "fixes" this blind spot by filling in missing information so that we do not notice the blind spots in normal daily activities. Several studies have been done to determine how the brain supplements this phenomenon. Recent studies have shown that someone seeking chiropractic treatment produces uneven blind spots due to musculoskeletal mismatch.
Chiropractic has developed a technology mainly used as a diagnostic technique for detecting "unequal blind spots" in the claimed eye. The blind spot arguing that it is amplified can diagnose brain dysfunction. These studies have been severely criticized because they raise some non-logical rationale (Hall, 2003). Hall has found some areas of discussion in the design of these experiments. In addition, some chiropractors claim to "eliminate awkwardness" by increasing the patient's peripheral vision. Because the blind spot is in the main view, not the surrounding vision, these descriptions are completely unfounded. These doctors caused confusion with the blind spots caused by mirrors, not by eyes during driving (Hall, 2003). Although the academic reliability of these studies is low, we provide a useful tool for mapping the blind spots of the research population of this study.
In this study we measure the blind spots of a group of athletes and a group of non-athletes using a method of mapping blind spots in the chiropractic field. This study supports the hypothesis that groups other than athletes have large blind spots due to the overall decline in health. The presence of the blind spot of each eye is a spontaneous anatomical feature and therefore rarely attracts academic attention. Research on how our brain "compensates" for this phenomenon has paid limited attention, but once it is explained it has received little attention. If you notice, you can find the blind spot. There is a simple visual test included in Appendix I. This will help people "see" the blind spot of the right eye.
The blind spot (a in the figure) is not a serious problem as the blind spot caused by the left eye is not in the same place as the blind spot caused by the right eye. In other words, a good eye of two eyes, the view of one eye covers the blind spot of the other eye and vice versa. What is said that craniofacial eyes are better than vertebrate eyes? In 1984, the Italian biologist team pointed out that the eyes of cephalopods are not as physiologically as the eyes of vertebrates. In vertebrate eyes, the initial processing of the visual image is done in the retina in the immediate vicinity of neurons next to the photoreceptor cells. In craniofacial eyes, nerve impulses from photoreceptor cells have to travel all the way to the brain for processing. Therefore, the eye of the cephalopod is "mere" passive "retina" which can encode information little by little, encoded in a much more complex way than vertebrates.
