UBERON:0000970 EFO:0000827 Note that whilst this is classified as an organ, it is in fact more of a unit composed of different structures: in Drosophila, it includes the interommatidial bristle as a part; we consider here the vertebrate eye to include the eyeball/eye proper as a part, with the eye having as parts (when present): eyelids, conjuctiva, This class encompasses a variety of light-detecting structures from different phyla with no implication of homology, from the compound insect eye to the vertebrate camera-type eye (distinct classes are provided for each) Wikipedia:Eye visual apparatus MAT:0000140 OpenCyc:Mx4rvViTvpwpEbGdrcN5Y29ycA visual system
