It can be minimized but it will always be present to some minor degree in even the best-designed roof-prism glasses. I have noticed it least in the very late East German 7x40 EDF BGA's, which are the finest binoculars I have ever used; the Docter 10x40 BGA Asphericals also minimize the problem. Normally, in binoculars with collapsible eyecups, folding 'em down and wearing glasses seems to minimize the blacking-out.
