can someone explained to me what the advantage of a closed-off optic is for pistols?

can someone explained to me what the advantage of a closed-off optic is for pistols? wouldn't having it be "open-top" mean that you can acquire the dot before it's eye-level?

    Why does the red dot enjoyer have a large pointed nose?

    You can't. Have you never fired a gun with a red dot before? Do you not even understand what they do in principle?

      Are you a fricking mongoloid?
      Of course you can acquire a red dot as you draw. It doesn't have to be at eye level if you use your peripheral vision in your draw stroke.

            Go into a dark room. Crank your dot up to max. You can literally see light emitting from the reflection on the lens reflect to where your eye would be if you were looking through it. That’s how dots work. That light reflecting off the lens is how you see the dot.

                The reflection of the lens has to be lined up with your eye for you to be able to see the dot. You cannot see the dot at such a wide angle as drawn in the OP.

                If you are seeing the dot in your peripheral vision it is because you have that part of the lens lined up with your eye. It has NOTHING to do with the emitter being enclosed or not, the “fov” of the reflection is the same no matter what.

                I think I've misunderstood your original point/thought process on this matter. I do not consider eye level and aligned with your eye to be the same thing.
                Eye level is pistol above shoulders. Aligned with your eye can happen below the belt.
                Thank you for the graphics but I understand how a red dot works.

                I realized there was a misunderstanding, but what makes dots like the ARCO (I haven’t seen one) harder to use is that the lens of enclosed dots tends to be smaller and harder to line up with the eye, but some say that looking through a tube is easier since you can index off the front and rear of the tube to line them up to project the dot into your eye. The bigger the lens the easier they are to reflect light back into your eye.

                IIRC with night vision you can see people’s red dots emitting beams of light if they are cranked up high

                Sounds more like you keep the sight in line with your eye fore the entire draw. Which is possible but also makes your argument irrelevant.

            Of course it has to be lined up at the target. It DOES NOT need to be at eye level before you are able to acquire the dot. Maybe it's necessary to be at eye level if you're asian (not sure how their peripherals work).

            You are moronic and conflating something that happens with pretty much random chance with a mechanical difference which does not exist in reality. If you happen to catch your dot in your peripheral vision with an open red dot, the same would happen with an enclosed, the two have essentially the same field of view. Look at this SRS, a red dot widely regarded as having a superior field of view over its competitors. Notice how the rear aperture/sealing glass are quite a bit smaller than the objective/collimator? And yet the field of view is larger than a Comp M2 which has the same size rear and front glass?

              It's not random if it's repeatable every time I draw.

                This is unique to your biomechanics and training. In my own experience and the vast majority of people I've shot with, the dot comes into vision at eye level as they press the pistol out and it comes into final alignment. No one I shoot with has the pistol extended as they raise it, which means that the sights are almost certainly not in alignment while the pistol is still below their eyeline in their peripheral vision.

                That's honestly quite interesting and is something to think about moving forward. I'm the only one in my group of friends that uses pistol optics so I just assumed that this was normal not unique. Sorry for insulting the roundness of your eyes senpai

                Not him but I think it’s just you have a funky draw. Basically you have the gun in a low ready during the draw - lined up with your eyes, while others only line up the gun and sights in the final stage. I practice a few draws, but none like that.

                So, do you think this a good thing or something that I need to retrain away from. As of rn my draw to round on target fluctuates between .45 and .7
                I don't feel that it's hurting my by any means but... if it can be improved

                Here's an ancient article for you, anon:
                https://www.tactical-life.com/lifestyle/firearm-training/press-out-vs-index-quick-draw/

                One added disadvantage to index not mentioned is that if you're all amped up on adrenaline and overdriving the gun, index can overshoot your eyeline as you present. That's entirely a training issue, but it's 100% avoided with a press out presentation since you're muscling the gun out toward the target at that point anyways.

                An addendum, this is specifically talking about draws or presentation after movement, etc. If you're just transitioning between targets in an array or something, then obviously the pistol is already aligned and you can probably maintain the dot in your peripheral as you look to the next target(s).

              In fact, some would argue that it's easier (requires less training) to rapidly acquire the dot on a fully enclosed sight because you instinctively align the body of the sight like your would iron sights, quickly bringing it into alignment and the dot into your vision. As opposed to an open red dot where you only have the single reference point of the front glass/frame and instead have to look away from the sight itself to the slide or existing irons to get lined up.
              This is of course without having sufficient training time and built muscle memory to have it aligned without having to look and search for reference.

        Not only does it have to be at eye level, it essentially has to already be lined up with the target.

    For one, durability. There's more structural material so you'd need more force to damage the important bits inside.

    For another, you don't want to acquire the dot before it's eye level. In fact, part of the appeal of reflex sights is that you don't see the dot unless the sights are in line with your eye. This stops you from getting false positives.

    Durability and enclosed emitter. If anything gets on the emitter in an open dot, your projected dot looks fricked up or may not show. An enclosed emitter ensures that nothing gets on the emitter, and the dot is always projected correctly in the glass.
    Also easier to wipe off the glass if moisture or muck gets on it.

    Having the emitter that projects the dot onto the glass enclosed prevents rain, dust, etc. from obstructing it and making the dot hard/impossible to see. As you would know if you'd ever used a red dot sight in real life, you can't see the dot until the optic is already lined up between your eye and the target, so having it enclosed doesn't create any usability issues that weren't already there.

    Do you understand how sights work?
    Any sights, even Iron Sights?

    I think you've never used an optic or even sighted down a firearm.
