Welcome to the collection of images dedicated to the amazing anatomical structure of the human eye—the iris! The iris, known for its unique shape and variety of textures, plays a key role in regulating the amount of light entering the eye. It is located around the pupil and creates a vibrant contrast with the sclera, making it an important element of the visual system.

Structure and Features

The iris consists of two main layers: the stroma and the pigmented epithelium. The stroma is made up of connective tissue and contains numerous vessels and cells, giving the iris its distinctive appearance. The pigmented epithelium is responsible for eye color, which can range from light blue to deep brown, depending on the quantity and distribution of melanocytes.

Surroundings

The iris exists in the context of the entire eye, interacting with the cornea and lens. These elements work in synergy to form a complete visual system that facilitates the perception of the surrounding world. The iris can also exhibit characteristic markings influenced by genetic factors and environmental conditions.

Impact of Seasonal Changes

While the iris remains constant in its structure, its perception can change depending on lighting and environmental conditions. For example, a bright sunny day can highlight its color and texture, adding depth and variety to images. It is also interesting to note that the iris can respond to emotional and physical factors, making it a dynamic part of the eye system.
