Real Images

In an experiment to find the focal length of a convex lens, we place the object needle on the one side of the lens and tries to set the image needle on the other side of the lens such that the inverted object needle and the image needle moves tip to tip when we move our eyes laterally. Here's the question: How we are able to see the inverted real image of the object needle without any screen?

Refer to this video.

Actually the image formed is inverted and real . But real image require a screen to be seen. So how can we see the real image without any screen?
