Unity cornea uses realtime reflections, not full internal optical refraction.

Other Unity versions and mobile devices have not been tested.

Realistic Human Eyes by NEFASA provides customizable eye assets for 3D characters.

Includes single-eye and eye-pair prefabs, six iris color presets, adjustable iris colors and pupil size, optional optic nerves, and three levels of detail (LODs).

Adjust color, pigmentation, vessels, iris relief, limbal ring, gloss and moisture through the Unity Inspector or the included editor window.

URP is supplied as the base package. Built-in and HDRP variants are included as separate importable packages. Follow the setup guide and import only the variant matching your project. URP/HDRP require the matching Unity render-pipeline packages.
