It could very well be, that I am noch looking though the center of my glasses when aiming.
Is there any way to figure that out without aiming at somebody (with a unloaded pistol, of course..
You really do need to know your dominant eye, particularly since you have eyesight issues. The dominant eye is important in everything from firearms to archery to golf.
Most right-handed people are right-eye dominant. Most left-handed people are left-eye dominant. Some people are cross-dominant. They are right-handed but left-eye dominant, or vice versa. The dominant shooting eye may likely make a large physical difference on how you shoulder a rifle or shotgun - but it's also important for handguns. The few millimeters you will alter your aim can make all the difference down range, particularly for the cross-dominant.
There are many different methods to find out, and should all have the same results. Try different ones to be sure.
The simplest is to point your finger at a distant object with both eyes open. First close one eye and then the other. Your finger will remain lined up with the object when your dominant eye is open. If your finger isn't directly between your eyes, this method may fail.
In class, I have a paper on the wall with a red dot on it. I give the students an index card with a hole punched in it. They hold the card out with both hands at arm's length, elbows locked, and slowly move it toward their face while keeping the red dot in focus. The eye it ends up on is their dominant eye.
Another method is to put your hands straight out in front of you while looking at a distant object. Cross your hands so as to form a small triangle between your thumbs and fingers. Same thing - keep the object in the triangle while you move your hands to your face. The eye you end up on is your dominant eye.
