Abstract
This study introduces a paradigm shift in pediatric visual assessment by leveraging objective eye tracking and gamified engagement to transform contrast sensitivity testing into a scalable, child-friendly process. The ETGCSF tool demonstrated strong reliability and markedly improved efficiency in assessing CSF in preschool children aged 3 to 6 years. These findings support ETGCSF as a promising tool for real-world clinical practice, and its modular design holds potential for future adaptations ranging from streamlined rapid screening in very young children to full CSF profiling for research.
