For each object keep two spheres: largest (that contains object) and smallest (than is contained in object).
If ray is outside largest it is not a hit
If it is inside the smallest, it is a hit
Only for rays that hit one sphere and miss the other we have to increase our accuracy by more spheres/better searching

(see this)
