Eye Concept v1 — Z-Image Turbo

Hyper-Realistic Iris Detail | Natural Eye Integration

Eye Concept v1 is a dedicated detail LoRA for Z-Image Turbo that enhances eye realism by improving iris structure, natural moisture behavior, and skin integration around the eyes.

This LoRA focuses on believable realism — not style replacement.
It strengthens the eye as a physical element within the face while preserving identity, lighting, and composition.

Eye Concept is designed to remain stable in complex scenes, multiple subjects, and long prompts.

Key Features

Optimized for Z-Image Turbo
Built specifically for Z-Image Turbo behavior and prompt handling.

Hyper-Realistic Iris Structure
Enhances internal fiber detail, color variation, and natural limbal ring definition.

Natural Moisture & Catchlight Behavior
Produces believable tear-line reflections and eye moisture without artificial shine.

Non-Plastic Skin Integration
Improves eyelid folds, lash roots, and micro-skin transitions to avoid the “plastic” look.

Stable Under Heavy Prompts
Tested with long prompts (600+ tokens), multiple subjects, movement, and outdoor scenes.

Non-Style LoRA
Does not impose a look — it enhances realism while respecting the base model.
