If we are tracing rays from the camera, how do we handle rays which don't end up back at the light source?

If the light source is infinitely far away, wouldn't this mean that there are an infinite amount of rays that would hit the object? Is there a way of optimizing this so that we can filter out the ones that matter the most or have the most impact on the lighting?
