Infant Visual Development

An examination of the visual system's maturation process during the first months of life, focusing on its capabilities and limitations.

Visual Acuity

Explanation of the limited sharpness and clarity of vision at birth. Typical acuity ranges and the biological reasons for this reduced resolution are discussed, including the incomplete development of the retina, particularly the fovea, and the visual cortex.

Color Perception

Description of the development of color discrimination abilities. Initially, preference for high-contrast colors, like black and white, is prevalent. The maturation of cone cells in the retina and their contribution to expanded color perception are explained.

Depth Perception

Exploration of the emergence of depth perception. Discussion of the monocular and binocular cues that facilitate three-dimensional spatial awareness. The development of binocular vision and its role in stereopsis are detailed.

Focusing Ability

Analysis of the eye's ability to accommodate and focus on objects at varying distances. Explanation of the limited focal range and the gradual improvement in focusing skills during the early months. The role of the ciliary muscles and lens in achieving clear vision is highlighted.

Eye Movement and Tracking

Investigation of the coordination and control of eye movements. Description of the initial jerky and uncoordinated saccades, and the gradual development of smooth pursuit eye movements for tracking moving objects. The neurological mechanisms underlying eye movement control are explored.

Visual Preferences

Overview of innate visual preferences, including attraction to faces, particularly the mother's face. The role of contrast, symmetry, and movement in capturing attention is discussed. The evolutionary significance of these preferences is considered.
