theta = -np.arcsin(np.clip((i_y0 - e_y0) / eyeball_radius, -1.0, 1.0))
phi = np.arcsin(np.clip((i_x0 - e_x0) / (eyeball_radius * -np.cos(theta)),-1.0, 1.0))
i dont understand this fomula ...

Have you already discover the meaning of this formula?
I also wonder why there is a negative sign in front of the formula, and I am confused about the value I got........ it is weird, and I don't know whether it is correct or not?
I assumed the outcome is radians, so I transform it into degree. After the transformation, the degree value is not correct, however, the result shows fine to me via function draw_gaze.
All I want to get is the degree form of theta and phi, but no clues for me at this moment.
