I am seated at point a. A mirror is in front of me at point b. Two objects behind me, one 5 ft behind me, point c. Another 10 ft behind me, point d. My eyes must change focus to clearly observe the two objects in the mirror exactly as they would if I turned and looked directly at the objects. ... Reckon why that is. Seems like to me a mirrors image, (two dimensional) would be the same as looking at a picture of the images reflected thereupon. ??

The mirror is 2D, but the *image* is 3D. The light bouncing off the mirror acts exactly as if there was actually something behind the mirror. So the eye has to focus just like it would for something far away.

The image may appear 2D, but in reality there's no difference between looking in a mirror and looking directly at it. It takes a little effort to conceptualize, but light reflected from a mirror still folllows a straight line, it just goes around a corner. If that makes any sense...

Well the image may be 2d, you still have to consider depth perception. You know how rearview mirrors on car's say object's may be closer than they appear. Fortunately usually the brain is preproggrammed to do this very quickly. Evolution or God was one heck of a proggrammer. ;)

be the same as looking at two pictures at say 10 and 15 feet distance still counts light has to travel from the object to your eye.
