which is the main purpose of a vision statement
Mission statement It is important that a mission statement is not confused with a vision statement. As discussed earlier, the main purpose of a mission statement is to get across the ambitions of an organisation in a short and simple fashion, it is not necessary to go into detail for the mission statement which is evident in examples given. The reason why it is important that a mission statement and vision statement are not confused is because they both serve different purposes. Vision statements tend to be more related to strategic planning and lean more towards discussing where a company aims to be in the future.
Blind spot (vision) A blind spot, scotoma, is an obscurity 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.[2] Because there are no cells to detect light on the optic disc, the corresponding part of the field of vision is invisible. Some process in our brains interpolates the blind spot based on surrounding detail and information from the other eye, so we do not normally perceive the blind spot.
