Development of Central and Peripheral Vision and Visual Field Asymmetries from Preschoolers to Adults

This study explored how meridian, eccentricity, contrast, and age influence the development of central and peripheral visual acuity (VA) in 37 children (aged 4-12)-divided into three groups-and eight adults. Psychophysical methods were used to measure VA using Lea symbols at contrast levels of 40% and 80%, measured at the fovea and at eccentricities of 2°, 4°, 6°, and 8° along the superior, inferior, right, and left meridians. The results showed that children aged 6 to <8 years had already achie
