Context:Amakati anombono omuhle kakhulu ebusuku futhi angabona kuphela ingxenye yesithupha yezinga lokukhanya elidingekayo ekuboneni komuntu.: 43 Lokhu ngokwengxenye kuwumphumela wamehlo amakati anetapetum lucidum, ekhanyisa noma yikuphi ukukhanya okudlula ku-retina kubuyele esweni, ngaleyo ndlela kwandise ukuzwela kweso ekukhanyeni okufiphele.
