Optik №1 is a pair of acetate spectacles built end-to-end in Blender 4.5 — modelled, textured, rigged and animated — then exported as glTF and played back live with three.js. In the browser you pick a frame finish and a lens, dial in a prescription on lenses with real refraction, and step into sunlight to watch photochromic glass darken. A Cycles-rendered film and the source files ship alongside the live scene.
