ELI5: How come if atoms are around 90% empty space in volume, yet solid matters are not transparent?

Matter is made of atoms and atoms are largely empty space. If we are made of atoms, we should not be seen as continious, non-spaced solid things with our bare eyes. Shouldn’t we appear as 90% empty space?

I mean if you grab a magnifying glass and look at the screen you are reading this off of, you have thousands of tiny pixels separated in space which when displayed in the density that they are, and at the distance from you that they are, appear to be 100% completely filled in solid color. 

The gaps between "stuff" are only relevant if the observer is on a size scale that can meaningfully see those gaps. 

Transparent would suggest that the light would just travel through an object, never obstructed. While light could get a decent distance unobstructed, the number of atoms light would have to conveniently "not hit" is far too many for transparency to be possible.
