How can our eye change focus?

A good example of this is when you’re looking at semi reflective glass windows, you can focus on the reflection you’re obviously seeing but the actual glass characteristics can be a little blurry, but then you can change your focus and the reflection becomes blurry but now you can see the glass characteristics such scratches on the surface for example.
How does the human eye do that?

You have tiny muscles in your eye called “ciliary muscles” that change the shape of the lenses. Like a camera lens mechanism that lengthens and shortens, flattening or bending the lens in the eye changes how light hits the retina at the back of the eyeball.
