About

This study aimed to design and validate a VR-based ophthalmic clinic that replicates traditional tests of visual acuity, stereopsis, and contrast sensitivity within an immersive digital environment. Using a rigorously developed system based onprogrammable interfaces, and standardized testing paradigms, we compared VR assessments against gold-standard clinical tools in a cohort of healthy adult participants. Key outcomes included test consistency, correlation, user acceptability, visual fatigue, and time efficiency. Our findings offer evidence for the viability of VR as a platform for remote ophthalmic testing and pave the way for scalable digital eye care delivery.
