When my binoculars are focussed in the centre, the edge is out of focus. Is this a design flaw or something that can be fixed?

Hi Dunbar, welcome to BirdForum.
Are these new binoculars? What brand and model are they? And how much is it out of focus at the edges? In cheaper brands, this can happen, but you can also get faulty specimens.
