發射説（extramission theory），眼睛會發射出一種“焰光”或“焰流”，當焰光接觸到任何物體時，眼睛會感覺到這物體，因此產生視覺。
主張發射説的哲學者有畢達哥拉斯和其學生奧克麥安（Alcmaeon）等等。這理論的形成與希臘大眾文化有關，希臘人對於視覺理解為，眼睛發射出的焰光會偵測物體表面。
希臘人常用觸覺來類比視覺。天文學者喜帕恰斯解釋，從眼睛射出的焰光像一隻‘視手’般地工作。]]> 2024-10-18 01:43:18 UTC https://padlet.com/tqjh40785/a16hpfx90xh8gzsw/wish/3175298895 tqjh40785 https://padlet.com/tqjh40785/a16hpfx90xh8gzsw/wish/3175298896 眼睛不會發出火焰]]> 2024-10-18 01:43:18 UTC https://padlet.com/tqjh40785/a16hpfx90xh8gzsw/wish/3175298896 tqjh40785 https://padlet.com/tqjh40785/a16hpfx90xh8gzsw/wish/3175298897 眼睛不可能發射出火焰]]> 2024-10-18 01:43:18 UTC https://padlet.com/tqjh40785/a16hpfx90xh8gzsw/wish/3175298897 tqjh40785 https://padlet.com/tqjh40785/a16hpfx90xh8gzsw/wish/3175298899 2024-10-18 01:43:18 UTC https://padlet.com/tqjh40785/a16hpfx90xh8gzsw/wish/3175298899 tqjh40785 https://padlet.com/tqjh40785/a16hpfx90xh8gzsw/wish/3175298900 眼睛不會噴火

認為在眼睛與物體之間存在某種均勻介質，這介質與進入説的附制體、發射説的焰光無關，是一種主要功能為傳輸視像的以太。這介質需要日光的作用才能工作，否則會變得不透明。]]> 2024-10-18 01:43:18 UTC https://padlet.com/tqjh40785/a16hpfx90xh8gzsw/wish/3175299005 tqjh40785
