Should these have something in them?

These look like they need to be shading gadgets of some sort, however I don't see how nicely they may work with them being empty within the center. These are on the second ground of some residences. These are repeated over each one of many condominium blocks second ground over These home windows, it doesn’t matter what route they’re going through, and all of them are empty like these two. The within of the home windows is into the principle residing space if that helps explains these.
