1. An apparatus comprising:
at least one processor; and
at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:
track eye positions of a user during simultaneous display of first and second content to the user, wherein the first content comprises content displayed by a head-worn display device so that it is perceived by the user as located at a first distance from the user and the second content is displayed by a display screen of a further display device located at a second distance from the user;
modify, responsive to the difference between the first and second distance being below a predetermined threshold, the display of either, or both, of the first and second content such as to modify a spatial position at which they appear with respect to one another;
determine which of the displayed first and second content the user is looking at based at least on eye position movements, if any, tracked subsequent to the modifying;
cause change of the display of the other one of the first and second content which the user is not determined to be looking at such as to reduce its visibility relative to the content that the user is determined to be looking at.
