Answer the following questions:
A virtual image, we always say, cannot be caught on a screen. Yet when we ‘see’ a virtual image, we are obviously bringing it on to the ‘screen’ (i.e., the retina) of our eye. Is there a contradiction?

When the reflected or refracted rays are divergent, the image is virtual. The divergent rays can be converged on to a screen with the help of a suitable converging lens. The convex lens of the eye performs this function precisely. In this case, the virtual image being seen on the retina, serves as the virtual object for the lens to produce a real image.

Note: Here the screen is not located at the position of the virtual image.
