Prism lenses are special lenses that are prescribed by eye doctors in order to help with eye alignment. They do not contain any focusing power, and therefore cannot correct any refractive errors. Prism correction helps correct eye alignment so that you only see one clear image. Prism lenses are usually recommended to patients who struggle with double vision, blurred vision, headaches, or other symptoms caused by slight eye misalignment.
