I have a torus where I wrapped a spiral curve around using the shrinkwrap modifier. After that, I created an array and curve modifier on the "eyes" object as I want it to follow the spiral curve. The array has a constant offset on X and the curve modifier is set to the spiral curve. Now the problem is that the normals are pointing in the wrong directions.

As you can see here, the normals are pointing to all kinds of directions As you can see here, the normals are pointing to all kinds of directions

As you can see in the picture only the circled row is pointing right As you can see in the picture only the circled row is pointing right

How could I control the normals of the spiral curve or how can I make sure the eyes object is facing outside like the circled row?
