Always adjust the parallax setting to Infinity (the Infinity setting looks like an elongated, horizontal "figure eight") prior to adjusting the eyepiece. If the scope is a variable model, turn the magnification to the highest setting.
Below is the correct procedure for Diopter (Ocular/Eyepiece) adjustment for both fixed and variable power scopes. The procedure is the same regardless of scope manufacturer, or whether the objective/parallax focus is on the objective ring or is a side focus type.
<span style="font-weight: bold">NOTE:</span> If the scope is a fixed power unit skip steps 1 and 2 as they do not apply.
(1) Turn the magnification ring to maximum (highest power).
(2) Turn the Parallax focus to "Infinity" (the symbol for Infinity looks like a figure eight). <span style="font-weight: bold">NOTE:</span> Most non-side focus scopes use a ring on the objective bell to adjust parallax, and the distances are usually numbered. Side focus parallax adjustment knobs may or may not have distances marked.
(3) Turn the ocular bell/eyepiece all the way in.
(4) Aim the scope at a cloudless section of the sky (you don't want anything except sky in the view, or else your eye will naturally attempt to focus on the object in the view beyond the reticle.
(5) Look at something nearby, but not too close, then look through the scope at the reticle. If the reticle is out-of-focus turn it a bit to begin to focusing the reticle, but look away from the scope. Never look at the reticle for more than a couple of seconds when adjusting the eyepiece (if you look at the reticle for more than a second or two your eye will naturally begin to adjust to bring the reticle into focus - and you don't want this to happen. <span style="font-style: italic"><span style="font-weight: bold">You want to be able to look through the scope and see a sharply focused reticle immediately with your eye relaxed</span></span>). This cannot be achieved by continuously looking through the scope and turning the eyepiece into focus in one continous motion because your eye will have already begun to adjust.
Remember, look away every few seconds and make small adjustments to dial-in the Ocular/Eyepiece focus. Once you have achieved this, you should not adjust the eyepiece at all, except to maintain proper focus as your vision changes over time <span style="font-style: italic">(it always does).</span> You may want to put a pen mark on the eyepiece indexed to the index dot on the scope tube - if the tube doesn't have an index mark use a pencil. That way, if someone else shoots your rifle and adjusts the Ocular you know where to return the adjustment to.
However, if you still cannot achieve simultaneous reticle and image focus after following the above directions for Eyepiece/Ocular Focus, it is <span style="font-style: italic">possible</span> that there is a problem with the scope.

Yes. Adjustment of the Diopter setting affects the Parallax setting, so you should re-zero to confirm that your zero is still valid.
