I just noticed recently when I close one of my eyes to read, the text appears to have depth, like this photo here:

It is not that exaggerated like the photo is, but I can see this (I don't know the English word for this effect) but it is slightly than the photo, it is kind of funny when you jump a line the text you are focusing have an effect, kind of a button being pressed
I suggest people do this and post here, just close one oeyef your eyez and try to read a text.
Also, another thing I noticed for ages is when I close one of my eyes, the opened eyes gets a slightly reddish area around the nose bridge region, I think The opened eye is seeing what the closed eye is seeing too?
