With the significant developments of extended reality (XR) technologies, the evaluation of the fidelity and practical applicability of immersive virtual reality (IVR) in replacing real-world shopping tasks is becoming increasingly important. In this paper, a virtual environment (VE) was used with a state-of-the-art head-mounted display (HMD) to evaluate participants' visual perception of IVR compared to reality. A visual acuity test demonstrates that in the IVR, participants experienced a significant decline of 37.1% compared to their real-world eyesight test score. Additionally, participants were asked to compare real furniture with their counterparts in an IVR, to complete Likert-scale questions assessing their perception of visual realism. This study initially reveals that IVR has the ability to convey the basic visual information of displayed virtual furniture objects.
