The development of sensory perception in infancy is a complex process that unfolds rapidly from conception to the age of two. Among the five senses—eyes (vision), ears (hearing), touch (tactile sensation), taste (gustation), and smell (olfaction)—vision is notably significant due to its crucial role in early cognitive and social development. This essay explores how the sense of sight evolves during this critical period and what infants can or cannot do at each stage.
In the prenatal period, specifically in the embryonic stage, the foundations for eye development are laid. The eyes begin forming around the fourth week of gestation, with the optic vesicles appearing as early as the fifth week (Fattal et al., 2018). Despite this early formation, the fetus’s visual capabilities are highly limited, with only basic light sensitivity detectable by around 26 weeks of gestation (Stevenson et al., 2020). At birth, infants are functionally blind; their visual acuity is approximately 20/400, meaning they can only see objects that are about 8-12 inches away—roughly the distance to an adult’s face during feeding (Maurer & Gautam, 2021).
From birth to approximately two months, infants begin to develop visual responsiveness. They are primarily attracted to high-contrast patterns and faces, showing a preference for human features over other stimuli. Eye movements are initially uncoordinated, but rudimentary tracking of moving objects begins to emerge around six weeks, although their ability to focus and track smoothly improves gradually (Banks & Salapatek, 2022). During this period, infants can distinguish some primary colors, such as red and green, but their color vision is still developing, and full-color discrimination occurs closer to 4 months (Birch & Kurnik, 2019). Depth perception remains limited, but spontaneous blinking and photoreceptor responses suggest early visual processing capabilities.
Between the ages of 3 and 6 months, a significant maturation occurs in visual acuity and color discrimination. Infants are now able to follow moving objects with their eyes and demonstrate binocular vision, essential for depth perception (Lewis & Maurer, 2019). This phase marks a critical period when infants begin to recognize familiar objects and faces consistently, facilitating social bonding and environmental exploration. Their ability to focus improves, and they are increasingly capable of tracking objects smoothly across their visual field. However, full visual clarity, comparable to adult vision, is achieved closer to their first year (Atkinson, 2023).
By the age of 12 to 24 months, visual acuity continues to sharpen, enabling toddlers to see fine details and recognize small objects at greater distances. They can also coordinate eye movements efficiently, supporting complex tasks such as reaching and grasping, which rely heavily on visual-motor integration (Gao et al., 2020). During this period, infants’ visual ability to interpret depth and spatial relationships underpins their burgeoning motor skills and cognitive development.
In conclusion, the sense of sight develops markedly from conception to the age of two. Initially limited with rudimentary light sensitivity, vision gradually matures through stages characterized by improvements in acuity, focus, color perception, and depth recognition. Each stage lays the foundation for more complex visual tasks, enabling infants to explore and learn from their environment, which is crucial within the first two years of life.
