Vision screening for children under three years of age who cannot read visual markers, such as those around one year of age, is generally inaccurate, but has some informational value. The primary purpose of early vision screening for children is to provide an aid in determining fundus disease or developmental status. Determination by observation of the child’s eye following and other conditions, such as through interest guidance, has some limitations in terms of accuracy. This approach tests the patience and experience of the screener and requires a high degree of cooperation from the child. Children have different visual characteristics at different stages of development. Since children around one year old cannot be trained or educated to read standardized children’s or E-word vision charts, they can only be screened by placing a roller with different thicknesses of stripes in front of their eyes and guiding their interest, which is less accurate but has some significance for reference. It is recommended that patients with abnormal vision screenings be seen promptly for evaluation and treatment as prescribed.
