Wait do regular eyes not have depth of field? I thought everyone had it since I've been near sighted my whole life

Regular eyes have depth of field. But unlike someone who’s near sighted, normal eyes can choose which depth is in-focus and which arr out of focus. 

If I hold a finger up in front of my face I can focus on it so it’s sharp and the rest of the room behind it is blurry, or I can focus on something in the background and then the finger is blurry.
