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.

Our eyes have a lens which focuses the light. The lens is flexible, so the muscles in our eyes can bend it and change its curvature, changing the focal length of the eye.
