Explanation of Color From a Prism. Although no one knows who invented the prism, Sir Isaac Newton was the one who discovered that the rainbows they produced were merely the components of white light that had been separated. Usually just called light or âvisible light,â white light comes from the sun.
Prism lenses may be prescribed by your optometrist for your eye glasses for double vision (or diplopia) depending on the eye condition you may have. Are you wondering how prism glasses work? â¢ Prism lenses are made from thin pieces of the optical material used in prescription eye glasses. â¢ Their apex is thinner and their base is thicker. With their light bending properties (or index of refraction), the light passing through is slowed down more through the base than through the apex.
