METHOD: The luminance threshold was measured on the different areas of central visual field (30º) with the program GIX of the OCTOPUS 1-2-3 perimeter in a group of 38 adults subjects with an without coated yellow lenses ( 482nm cut-off) under mesopic conditions. RESULTS: The luminance threshold improved through the yellow filter on the different established areas of visual field (30º) and the increase differential light sensitivity was statiscally significant (e.g. all visual field p=0.0003 and macular visual field (9.5º) p=0.0001. CONCLUSION: There is an improvement of luminance threshold and hence a greater luminance perception through yellow filter under mesopic conditions.engconference posteropen access617.7Yellow filterMesopic conditionsCentral visual fieldÓptica y optometríaÓptica oftálmicaÓptica geométrica e instrumental2209 Óptica2209.15 Optometría
