Homozygotes and hemizygotes have reduced and wedge-shaped eyes with a dark blood red colour and glassy texture due to fused facets. There is an irregular squeezable surface on the upper area of the eye.
Heterozygous females have wedge-shaped eyes, but the facet number in heterozygotes is approximately twice that seen in hemizygous males.
