Icons disappear on zoom out , so I need to zoom in very closely to see them

Every time, to see the icons on the map of the area, to find out what is around, I have to zoom in a lot (scale of a hundred meters in width). Otherwise, the icons simply are not displayed. But then I see only a small part of the map. Is it possible to somehow configure this so that I can see all the icons on a large scale of the map? I want to see all the available icons on large scales of the map. At the same time, some icons are displayed earlier when zooming in, and others later, and you are never sure whether all the icons are displayed until you zoom in very, very much. Thank you.
