    If you have double vision or your eyes have trouble converging for close work , then you can have a prism.

    A prism is for specific problems, it isn't something you can get just because you like the name of it.

    Prism is a wedge of glass. When it is prescribed in glasses, it is used to move an image to where it will make the eyes more comfortable. Larger prisms made of glass separate light in to the colors of the rainbow. They are often used in middle school science labs.
