In the standard geometric optics approximation, null rays propagating in a spherically symmetric black hole background follow planar geodesics. This picture changes, however, when the helicity-dependent effects of light are incorporated into the dynamics. Specifically, the interaction between the helicity of light and the spacetime curvature induces an angular deflection out of the geodesic plane. In this talk, we employ the spinoptics formalism to study light deflection due to the helicity-curvature interaction in a spherically symmetric hairy regular black hole solution obtained via gravitational decoupling. Our results reveal clear imprints of the hairy black hole parameter on the deflection angle.
