[[Vision in fish|Vision]] is an important [[sensory system]] in fish. Fish eyes are similar to those of [[terrestrial animal|terrestrial]] [[vertebrate]]s like [[bird vision|birds]] and mammals, but have a more [[spherical]] [[lens (anatomy)|lens]]. Their [[retina]]s generally have both [[rod cell|rods]] and [[cone cell|cones]] (for [[scotopic vision|scotopic]] and [[photopic vision]]); many species have [[colour vision]], often with three types of cone. Teleosts can see [[polarized light]]; some such as cyprinids have a fourth type of cone that detects [[ultraviolet]]. Amongst [[jawless fish]], the [[lamprey]] has well-developed eyes,while the [[hagfish]] has only primitive eye spots.

視覚は魚において重要な感覚系である。魚の目は陸生脊椎動物鳥類や哺乳類)の目と似ているが、より球状水晶体をもつ。彼らの網膜には一般に桿体錐体があり(薄明視明所視のため)、多くの種は色覚をもち、しばしば3種類の錐体を有する。硬骨魚類は偏光を見ることができ、コイ科のような一部は紫外線を検出する第4の錐体をもつ。無顎類の中では、ヤツメウナギはよく発達した目をもつが、ヌタウナギは原始的な眼点しかもたない。
