Well, I mostly meant, what is minimum amount of time that would be effective practice for seeing auras. It seems like for many skills, after a certain point more practice does not help much. E.g., double the time is not doubly as effective.

As for the rainbow effect wearing glasses, I'm not concerned whether that is the aura or not. I just figure that learning to see the aura makes a person more sensitive other things they did not see with their eyes before either. I have been getting the effect more and more, slowly, as time goes on. If

I'm not very new to seeing the aura. I've been practicing for months, on and off. I suppose less often after I started seeing it at all.

Occasionally I'll get very dull headaches, they don't bother me at all really, so I'm not concerned about that.

You say you spontaneously started seeing auras... do you know or have a theory of how that happened?
