For this objective, we utilize the metric-affine black hole geometry with the inclusion of dilation, spin, and shear charge. The Lagrangian coefficients $f_1$ and $d_1$ are the main parameters, where $f_1<0$, which differentiate the solutions by $d_1=8f_1,\\;d_1=-8f_1,\\;\\&\\;d_1=\\pm8f_1$. Based on these parameters, we carry out this work in two cases, i.e., $d_1=8f_1,\\;\\&\\;d_1=-8f_1$. We forecast the detailed impact of dilation, spin, and shear charges on the optical properties of the black holes in both cases.
