What is the Purpose of Prism in Eyeglasses? The simple definition of a prism is a solid object that has the same cross-section along the entire length of its shape. When you cut straight across an object, the cut portion is called a cross-section. Draw any shape using straight lines. Now use your imagination to see it extend upward and that is a prism.
