Poor functionality during shooting - ESS Advancer V12 Military Goggles

These goggles are designed like swimming goggles, in that they fit BELOW your eyebrows. Hence the problem whenever you aim with one eye closed, due to the following sequence of events:

1) You close your non-dominant eye (let's say left eye) to aim with your dominant (right) eye.
2) Deliberate closure of your left eye requires contraction of the left orbicularis oculi muscle - so your left eyebrow is pulled downward when you squeeze you left eye closed. This obviously does not happen with your right eye, because you are leaving it open to aim.
3) Your left eyebrow is then pulled BELOW the top rim of the left eyepiece frame - so your left eyebrow is now inside the left goggle, and your right eyebrow is still outside and above the right goggle.
4) You finish aiming / shooting, so you open your left eye again. Your left orbicularis relaxes, and your left brow now rises to its normal relaxed position.
5) Unfortunately, your left brow is trapped inside the goggle frame. Opening your left eye (by relaxing and therefore raising your left brow) pushes the whole left goggle up because your left eyebrow is trapped inside the left goggle, under the upper frame.
6) Now the goggles are angled and not fitting any longer, with the left goggle noticeably higher on your face compared to the right goggle. You also have some visual distortion, as the polycarbonate lenses are at slightly different angles relative to each other.

So every time you close and open your non-dominant eye in order to aim, you must manually reposition the goggle back below your brow on that side in order to see well again.

Talk about combat ineffective. Imagine having to reposition your goggles over and over during a firefight, every time you open your non-dominant eye.

For what it's worth, my brow anatomy is more-or-less completely average, middle of the bell curve. We've all seen people with extremely prominent brows (the "neanderthal" brow) or other significant variations in facial anatomy - I am none of those things.

Only buy these goggles if you have no realistic chance of having to shoot with one eye closed while wearing them. They work great as long as you never have to forcefully close one eye while keeping the other eye open.
Cons: Aiming with one eye closed disturbs the fit every time, requiring you to manually reposition the goggles.
