How could we see the image of ourselves in concave mirrors?

Physics Asked by Adidas10 on February 9, 2021

Let’s consider a case where observer AB (let’s suppose ‘you’) are standing on the radius of curvature of a concave mirror . The point A is your eye (as shown in the figure) and with the help of the ray diagram we can see that the image A’ of the eye is formed exactly below the point A and at the same distance from the principal axis. And that also means that all the light rays reflected from the eye intersect each other at point A’. But how can we see the image of our eye in the concave mirror if no light rays (that are reflected from the eye) reaches the retina of our eye?

(Since our eyes can see an object only if the light reflected by the object reaches the eyes.)
