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.
Eyepiece An eyepiece, or ocular lens, is a type of lens that is attached to a variety of optical devices such as telescopes and microscopes. It is so named because it is usually the lens that is closest to the eye when someone looks through the device. The objective lens or mirror collects light and brings it to focus creating an image. The eyepiece is placed near the focal point of the objective to magnify this image. The amount of magnification depends on the focal length of the eyepiece.
