A futuristic sci-fi monocle with a smooth metallic frame, featuring a single circular lens that glows softly in blue or green. The lens is slightly thick, made of advanced crystal-like material with a faint inner shimmer. Tiny mechanical details, like rotating micro-gears or subtle pulsating lights, line the edge. It attaches via a minimalist side arm or a sleek wraparound band behind the ear. The design is clean and advanced, blending retro elegance with high-tech functionality—perfect for a refined character in a sci-fi universe.
