Full Answer

According to the Encyclopaedia Britannica, The optic nerve does not have photoreceptors, such as rods or cones, which is why it is unable to detect images. The right eye’s blind spot is located to the right of the center of vision. The left eye’s blind spot is located to the left of the center of vision. When both eyes are open, the blind spots are not perceived because the visual fields of both eyes overlap. When one eye is closed it is difficult to detect because of the brain’s ability to fill in or ignore the missing parts of an image.
