Beyond the focal point, $f$, a convex lens only forms real image. However, I see an inverted virtual image of a distant object when looking at the lens from a distance.

If the image of the distant object converges near the focus and then diverges from that point towards our eyes then the image should appear to be in mid air, but it isn't. It's appears to be in the lens.

Why is that so?

Edit: if the image is from mid air it should look like a hologram doesn't it. But it doesn't look like one.

I post this as an answer, as I do not have enough reputation to post a comment. It should be easier to locate the image if the lens is far away enough from your eyes that you can see the image with both eyes, as you will be able to judge distances better. I recall having heard it from someone (if I recall well what he said, as I had the same question as you), I never verified it. But it looks sensible.
