How come my short-sightedness affects reflections?

Maybe biology, maybe physics. I’m not sure. Either way, I really can’t wrap my head around this

When I look in a mirror without my glasses on, everything in the ‘distance’ in the mirror is still blurry, but how can this be? All the light reaching my eye from that mirror is coming from the same place. The light can’t be out of focus before it reaches the mirror, so how come it can be when reflecting from the flat plane to my eye?

*Edit: I do understand how an image is produced in a mirror and how we perceive depth in a reflected image, but the fact is that the light is still reflecting off of a flat plane at a uniform distance – I can’t understand how that reflection can possibly have **actual** depth that can affect my shortsightedness*

The image in the mirror is not the distance from your eye to the mirror, it is the sum of the distance from your eye to the mirror and the mirror to the object you’re looking at.
