The effects of dark matter (DM) on the curvatures of the neutron star (NS) are examined by using the stiff and soft relativistic mean-field equation of states. The curvatures of the NSs are calculated with the variation of baryon density. It is found that the radial variation of different curvatures significantly affected by DM inside the star. The surface curvature is found to be more remarkable for the massive star. The effects of DM on the compactness of the maximum NS mass is less as compared to canonical star. The binding energy of the NS goes towards positive with the increase of DM momentum and makes the system unstable.
