Prisms, like double vision, seem to be pretty dreaded by most people (aside from strabismus specialists and optics fans). For testing purposes and clinical applications, we thankfully don't have to know a ton of things about prisms apart from the essential applications within our clinics. Hopefully this will help you understand the principles of prisms better so that you can use them effectively in clinic as well as answer any test questions that might pop up!
