vision problem! who's right?

I don't know if this is a stupid question but one day me and my friend were talking and we got into an argument about viewing a screen through a camera's phone and a phoropter with the same lense in both. Suppose that the lense is perfect for my eyesight and suppose that we have completely different strength in eyesight; I cannot see objects clearly without my glasses but he can. So when we visit the optometrist office and try to view images under that very same lense, it is suitable for me but not for him. Now in the case of viewing the screen under a camera, would it yield the same result? My friend insists that yes because in this case we will both be able to visualize the images on the display screen on the camera at the same quality because we are both viewing images under the same specifications set by the camera and because of this, therefore our eyes do not need to adjust at all because the camera does all the conversion behind the scenes.
So who's right? He says under the camera we will see the same thing but I say we won't because the lense should only work for me (since if it never worked for him in the optometrist's office it will not work on a camera's screen), I am no physicists but can anyone kindly explain this?
