To determine the effect of twilight myopia on retinal quality image and to explain the Purkinje effect, the numerical model of Gullstrand's eye was modified. Modification was concerning on addition of the iris in vision path and chromatic properties for the optical elements of modeled eye. Applied changes allowed to simulate propagation of light rays under photopic and mesopic vision conditions. The obtained results were used to simulate retinal spot diagrams, during day and under low light intensity, as in the case of twilight.
