Seeing in stripes

In this office there are vertical blinds made of broad strips of material that hang down - standard office types. When I look through these from a range of about 3 feet it is close enough that only a single eye can see through to a given section of the trees outside.

Now I have 1 eye that is moderately short sighted and one that is long. The result is that I see the trees in vertical bands of sharp detail and soft focus low contrast. And they join without a break or border. It's curious.
