A concave mirror can form both real, inverted images of various sizes and virtual, erect and enlarged images depending on the position of the object whereas a concave lens forms only virtual, diminished and erect images for all positions of the object A convex lens acts a lot like a concave mirror. Both converge parallel rays to a focal point, have positive focal lengths, and form images with similar characteristics. A concave lens acts a lot like a convex mirror. ... Concave mirrors form real and inverted images except when the object is between pole and focus.
