What will be the image seen to us if an object is placed in between the focus and pole of our eye lens ?
I guess no image will be formed.
What you'll see is a blurred image of the object. Why don't you try keeping a finger too close to your eye and see for yourself ?
The ray diagram will look somewhat like this :
You will not be able to see the image of the object kept inside your eye because none of the rays of light striking that object will reach the retina. There will be a black spot in the image of every object outside the eye because of the shadow of the object inside it. Image of a tree will look somewhat like this:
Our eye doesn't have a fixed focus. That being said, if you look at a distant object, our eyes' focal length becomes the distance between our eye's lens and that object. As Simha said, anything that is kept beyond or before the focus will appear blurry. This is more than obvious, and is a daily phenomenon that you would have discovered yourself too, although unknowingly.
