WebThe index of refraction, or IOR, is an optical measurement that describes the change in the direction a light ray is traveling. Essentially, the IOR value is used to determine how much the ray will be bent when it passes through one medium to another. For example, water has an IOR of 1.33, whereas plate glass has an IOR of 1.52.
