Because halo luminance is typically 2-5 orders of magnitude lower than that of the bright display region and is easily contaminated by lens stray light and eye glare, accurate quantification of halo visibility remains challenging. In this work, we propose a halo visibility model grounded in the human visual system (HVS) by combining measured halo luminance distributions with subjective evaluation. A measurement method is, to the best of our knowledge, first used to obtain two-dimensional halo luminance distributions, from which a perceptual halo-boundary model is then established to determine the perceptual halo area. Based on this, a halo visibility index (\n                    <jats:italic toggle=\"yes\">HVI<\/jats:italic>\n                    ) is defined as a logarithmic integration of the perceived contrast over the perceptual halo area in the field-of-view (FOV) domain. Experimental results show a strong correlation between\n                    <jats:italic toggle=\"yes\">HVI<\/jats:italic>\n                    and subjective scores (\n                    <jats:italic toggle=\"yes\">R<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    \u2009=\u20090.96).
