Shouldn’t they be clear if I am standing beside the mirror and have good short-distance sight?

They’re far away from the mirror. Your own sight doesn’t really matter.
A 20m tall tower in a side mirror only has maybe 10cm. There’s no room for the details to show up.
No, because the path the light took from the object to you is still long. The light isn’t *coming* *from* the mirror, it’s just bouncing off it. The mirror doesn’t do anything to focus or defocus any light hitting it, it just bounces back whatever hits it. If what’s hitting it is light from a far away object, the light coming off the mirror and into your eyes is still “light from a far away object”.

Your vision works by the lens in your eyes being able to focus light onto your retina. Focusing light is basically sorting light by the angle at which it is arriving at the lens. Light coming from distant objects comes in at a different angle relative to its surroundings than things close by.
A mirror just bounces light off it like a wall bounces a ball. It retains the angle of the incoming light so the eye still needs to sort light the same way for a distant object.

Like others have said, a mirror just reflects the light coming from the distant object. So, if the object is 100 meters from you and you are 1 meter away from the mirror, the image should look just like you were looking at the object 101 meters away. If it is not blurry when you look directly at the object, it should not be blurry when you look in the mirror.
