Create an extreme macro portrait photograph of a human eye photographed under controlled UV-A blacklight. The eye remains anatomically realistic. The iris contains subtle fluorescent structures that reveal patterns resembling branching biological networks. Tiny vessels, moisture droplets, eyelashes and microscopic surface textures become visible. Different portions of the iris emit subtle cyan, violet, emerald and magenta fluorescence. The cornea creates realistic reflections and refraction. The pupil remains deeply dark. Preserve realistic wetness, optical anatomy, subtle imperfections and natural skin texture around the eye. The result should feel like looking into a living microscopic galaxy while remaining completely photographic and scientifically plausible.
