Herein, we constructed a finite element human eyeball model, encompassing a biophysically detailed retinal layer, optic nerve segment, and its surrounding tissues, as well as extraocular electrodes.A multi-conductivity 3D human eye model was constructed based on the AC/DC module in COMSOL Multiphysics. This model encompassed essential eye structures, such as the cornea, atria, lens, vitreous body (VB), retinal, choroid, sclera.
