What outcome occurs when impurities cause local deviation in refractive indexes throughout a glass lens?

💡 Explanation

Impurity variation introduces variations in optical path lengths; because Interference, specifically *thin film interference*, between these paths causes constructive and destructive interference, an interference fringe pattern arises. Therefore it appears locally increased, rather than uniform transmission that would occur in pure optical glass.
