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.
This prism correction is used to treat muscular imbalance or other conditions (see vergence dysfunction) that cause errors in eye orientation, such as double-vision. Prism correction is measured in prism dioptres. A prescription that specifies prism correction will also specify the base, which is the direction of displacement.
