[QUOTE]I was using the eyepiece adjustment. Thought THAT was the parallax. Parallax is the infinity-200 yard knob? [QUOTE]
I think that is correct. What scope do you have?
That means I can set it up with either and it will be the same or really close to the other?
I am not sure what you mean by this. If you have a large correction for your vision and your rifle is set up for viewing with you wearing your glasses, you will have a problem trying to use it without your glasses.
If your vision is corrected to 20/20 with glasses and your scope is set up that way, then anyone with uncorrected 20/20 vision and those whose vision is corrected to 20/20 should be able to use your scope without further adjustment as long as the person wearing glasses is using them when he uses your rifle.
Put another way, if the scope is set up for someone with 20/20 vision, the scope does not care if you wear glasses or not as the assumption is that the eye viewing the target is corrected to 20/20.
