The recent thread about shifting groups made me think alot about this. I see alot of people have there diopters turned out quite a bit. Where with mine there turned all the way in. What does that mean exactly?
Diopter settings...

Depends on your eye sight. You should adjust the diopter (focus) so the reticle is clear and precise. There are at least a dozen YouTube videos explaining how to do this adjustment. In any case, it should be adjusted before you sight in the scope. Especially so, if the scope in question is an inexpensive one.

If u need reading glasses ,you need to back the diopter off. The older I get the more I back them. Before long I am going to run out of threads,lol. When a young shooter hands me his rifle i can barely see the ret.

Hmm maybe that's why then. I'm 27 with 20/20 vision. I've adjusted them out before but best is always all the way in so just was curious if I was alone on that or not.

It means you are a very sick man and nobody likes you! ;^) No, really I used to have good eyes like you way back when I was 50. Enjoy it while it's there cuz it doesn't last forever that's what the adjustable diopter/ocular bell is all about. It can be adjusted for us old folks so we don't need our glasses to see the reticle clearly which is a very nice thing.

One's eye sight isn't totally dependent on one's age. I turn 80 this month, and I have 20-10 in my left eye, and 20-15 in my right (at distance), and NO(!) cataracts! But... I use cheaters to read, and they're 2.25 diopters. Hence I do have to adjust my scopes accordingly.
There is another issue you might want to ask your ophthalmologist about. Most eyeglasses do not have full correction in the upper left quadrant (upper right if you're a left-hand shooter). However, glasses can be made special order which have full correction, or special correction, in almost any quadrant of the lens. If you shoot a lot, it may be worth the expense to have special hunting glasses made to order.

What model and power scope? Adjustment of ocular lens is differant for high powered scopes that are use in FT or BR.

Hey Dillon,
Just appreciate the fact that you don't know what a Diopter is for yet. That's why you can use that fixed 10 SWFA I sold you out to 500 yards..LOL When my close-up started going away I was really pissed off trying to shoot my pistols.....Then a few years ago I got into PCP's and started using scopes under 100 yds instead of PB's out to 500. My point here is the important thing to test for is parallax. I was using a very expensive scope yesterday at 35 yards with what I thought was a perfect diopter adjustment and the focus knob at 35.....I found 1/4" of parallax at that distance.....I adjusted out the parallax but the reticle isn't perfect anymore...Aging eyes can deceive and it varies with me sometimes at different distances...
ALWAYS CHECK PARALLAX !!
