WitrynaThis hole results in a “blind spot”. Finally, the fovea is a small area in the center of the retina that has only cone cells and is responsible for the most acute vision. Light reflected from an object enters the eye and a real, inverted image is formed on the retina. A blind spot, scotoma, is an obscuration of the visual field. A particular blind spot known as the physiological blind spot, "blind point", or punctum caecum in medical literature, is the place in the visual field that corresponds to the lack of light-detecting photoreceptor cells on the optic disc of the retina where the optic nerve passes through the optic disc. Because there are no cells to detect light on the optic disc, the corresponding part of the field of vision is invisible. Processes in the b…
