The thin lens equation shows that when there is an object further than the focal point, there is a real image formed on the other side of the lens, and this principle is used for cameras, eyes, etc.
However, when I take a converging lens(that I got from some mobile VR headset), and hold it between me and an object, both of whom are more than the focal length away from the lens, I see an upside-down virtual image of the object.
So my question is, why do I see a virtual image instead of a blur that I would see at the point where the real image forms? What would the ray diagram look like for this?
Here is a picture of this phenomenon:
