Eyes Textures

Eye textures refer to the visual patterns and details that make up the appearance of the eyes, typically when used in digital art, 3D modeling, and game development. These textures help bring realism and personality to characters by mimicking the intricate details of human or animal eyes. Below are some key aspects of eye textures:

1. Iris Texture

• Color: The iris is often depicted with colors ranging from blue, green, brown, hazel, and gray to more exotic shades like amber or violet. This color can have different tones and gradients.
• Pattern: The iris usually has intricate patterns of lines and radial streaks. These are often either striated (line-like) or have a more circular, petal-like appearance around the pupil.
• Detail: Some iris textures include variations such as specks, flecks, or a darker ring around the outer edge known as a "limbal ring." The iris may also have slight variations in color near the edges or center.

2. Pupil Texture

• Shape: The pupil is typically a circular or vertical slit shape, depending on the species (round for humans, slits for some animals like cats).
• Size: The pupil can appear to dilate or contract, influenced by lighting conditions. The texture of the pupil may include small variations and reflections, particularly in high-quality renderings.
• Reflection: There can be reflections within the pupil, such as highlights from a light source, which give the eyes a more lifelike appearance.

3. Sclera Texture (White of the Eye)

• Color: The sclera typically appears white, but it may have subtle variations, like veins or slight redness, which can be modeled or painted into the texture.
• Veins: Thin, red veins or capillaries may be visible, especially near the corners of the eye.
• Detail: The sclera is not entirely flat; it has minor bumps and textural details that add realism.

4. Cornea Texture

• Glossiness: The cornea, being a transparent layer over the iris and pupil, often has a glossy, reflective surface. This can be modeled with specular highlights or reflection maps to simulate the shine and moisture on the eye’s surface.
• Reflections: The surface may reflect its surroundings, including light sources, environments, or the shape of the eyelid above it.

5. Eyelashes and Eyebrows

• Lashes: Eyelashes may be modeled or painted in the texture, with natural curvature and varying lengths. They are typically darker than the sclera and the iris.
• Eyebrow: The eyebrows may be painted as part of the texture or modeled separately to add to the realism
