Do you see double of things you aren't focused on?

If I hold my finger in front of my face and unfocus mmy eyes, or focus on something further away, I see two semi-transparent images of my finger.

I thought that was the same for everyone. But tonight I found out that if my wife does that she just one finger, but it is blurry.

If you do this, do you see two fingers or one blurry finger?

[While trying to google this, I also discovered that some people can't unfocus their eyes.]

Assuming you can unfocus your eyes, unless you only have one functioning eye, you should see two fingers.

You've two eyes, spaced a few cm apart. They each have a slightly different perspective. When you focus on a subject, your brain combines the two images, creating a 3D image. When you focus on something beyond the subject, you see the two perspectives of the unfocused object in isolation, giving two slightly different versions of the image separated in space, and they appear semi-transparent because your brain is also receiving the image of what's behind the object from the opposite eye.

Yeah that's what I thought but my wife just sees one blurry one. Seemed like it could be one of those things where people's experience of the world commonly differs.

I recently discovered that by sticking my finger up my nose during a yawn (apply pressure on the Cartilage) it is impossible to stop that said yawn until you pull your goey finger out.
