The cross pattern (isogyres) formed by certain crystals when they are placed between crossed polarizers and illuminated with convergent light results from birefringent properties of the medium. A similar image is seen in refracting structures which exhibit little or no birefringence, such as the eye lens. This paper provides a mathematical explanation of the formation of isogyres by refraction.
