If there is one thing you need to understand about Duna, it is that the spice is a hell of drug. The spice melange, a substance found only on the planet Arakis, is a drug so powerful that the whole universe basically revolves around it. Space can significantly improve one's health, spend a person's life expectancy and can give people the opportunity to predict possible futures.

That last part is the most important of the people in the "Dina" universe Long abandoned “thinking machines,"So, amongerst the trip should be done by the people who drive the ship all the time instead of advanced computers. It is an impossible task unless the person is dosed on a lifetime to the point that they are hardly recognizable as human. Lynch film in 1984 and They looked pretty unusual.

Fortunately, most people in Duna books do not require so many spices to do their jobs, so they are rarely deformed. For regular people who eat spices in Duna, the only sign of their addiction is their unnatural blue eyes, which affect both their iris and their sclera. Outside of Arakis, many people will wear special contacts to hide the volume of their use of spices. For Fremen living in Arakis, where the spice is abundant and crucial to survive in such a cruel desert environment, it is more often to pride blue eyes.

The "Duna" films that have been made so far have shown many variations in how the spice-binetry eye will look like. In Lynch's film, Paul's eyes are a a lot Light blue, so much that you can't ignore it if you try. But out of Paul's visions in "Duna: Part One", Paul and Canie in Vilnev's films tend to have blue eyes that are much less pronounced. Depending on the lighting, the eyes often do not look so blue at all.

Meanwhile, the books have frustrated mentions that are so dependent on spices that the eyes are deeply consistent indigo, to the extent that you cannot distinguish between their students, iris or sleras. It is a view of the eyes that has not yet been seen on the screen in the series, for reasons that are not 100% clear. Is it because Vilnev thinks it will look stupid in a visual medium? It was a partial explanation of why "Game of Thrones" chose to omit the violet eyes of Danieris Targaryen, for example.

Perhaps the flaw so far is because Vilnev and the included writers save extreme blue eyes for the real dramatic moment. There is a scene in "Duna: Messiah" (It will soon adapt to "Duna: Third part") That many book fans are looking forward to, in which the character deliberately overdosed with spice in an attempt to improve their conscience, with great consequences. Maybe Vilnev's movies keep Really Blue eyes so that this scene will have a greater impact.

At a thematic level, it's hard not to wonder why Herbert chose Blue, as the far -reaching fantasy room offered the series the opportunity to choose any color she wanted. Maybe Herbert just liked the blue, or maybe he realized he was the best color to pick up books' General allegory of imperialism in the real world. After all, the dynamics between the Empire and the Fremen, with the more powerful group oppressing the desert people because of their Oil Spice deliberately reminiscent of the exploitation of the Western world in the Middle East oil areas. Having a large convoluted metaphor of the imperialist-dependent imperialists include blue eyes in that sense, because the United States (especially in the 60s, when the country was less racially diverse) has one of the highest concentrations of people with blue eyes in the world.

However, most likely, the reason for the blue eyes is even simpler: Frank Herbert was really in mushrooms, and his friend Paul Stemmet (another famous mushroom enthusiast) wrote in One of his books That Frank told him that Fremen's eyes were inspired by the color of Psilocibe mushrooms. Similar to the heavy dose of spice melange, psychocibe mushrooms are It is known to give you hallucinations If you enter them. As it explained:

"Frank continued to tell me that much of the premise of Duna - The magic spice (spores) that allowed the bending of space (knocking), giant worms (mushroom mushrooms), Freeman's eyes (Ferrule's blue from Psilocibe mushrooms), mysticism of female spiritual warriors, For Maria Sabina and the sacred cults of Mexico mushrooms) - they come from his perception of the fungal life cycle, and his imagination was stimulated through his experiences using magical mushrooms. "

See: It was the 1960s, the man and much of the attraction of the books "Duna" were their clear psychedelic qualities. The blue eyes of the Duna Universe are just a sequel to Herbert's readiness to become truly strange and experimentally with it; The fact that it also fits into the political themes of books is a fun bonus.
