After accepting her vampire-self and sucking Pip Bernadotte's blood, her eyes turn red permanently.
Whenever Seras uses her vampire powers her eyes turn from blue to red. Right before Alucard stops existing the eyes close. After Alucard absorbs Schrödinger's life, he has to perceive himself in order to exist, which is no longer possible since his life is one of three million in himself. It is later implied, that he is no longer himself by adapting parts of the others personalities. As stated later each eye represents a life (human or non-human) that Alucard absorbed at some point in his unlife. Alucard is able to summon a black mass with thousands eyes in it.

Serial Experiments Lain uses the size of the characters' pupils to indicate their varying states of mind as The Wired becomes more and more connected to the real world. The Jagan Eye in YuYu Hakusho is one of Hiei's major themes - it gives him several mental powers, as well as glowing when he uses Dark Flame techniques. Roy, who always looked towards the future, lost his eyesight. In addition every alchemist who had performed human transmutation must give up a part of their body symbolic of their motivations. Most of his attacks involve shadows, which are depicted as covered in eyes. People who're going insane frequently hallucinate faces (their own and others) being replaced with one with the symbol in place of its eyes. Pretty relevant since his "thing" is madness (distorted perception) born from paranoia (hence the extra eye). In Soul Eater Asura the Kishin has a symbol which consists of three eyes turned on their sides. Neon Genesis Evangelion and Rebuild features several including: SEELE's logo, Asuka's Eye Scream of EoE (and it's reference to it in Rebuild), Sahaquiel and several more if one looks for them. Each Millennium Item except for the Millennium Key in Yu-Gi-Oh! has an eye on it somewhere. The core members of the group are the Third Eye, who each have a hidden Third Eye because they were reincarnated via Forbidden Magic. Black Clover: The Eye of the Midnight Sun's symbol is three yellow eyes.
