Like you, I also recall that some people claimed there was a trick that made it possible to extend the eyecups fully, but personally I found that extension was easy to do and am sure I extended them to their maximum length.Regarding your experience with blackouts, the difference between the two different occasions might have been due to different light conditions: I think blackout issues are less severe on a bright day when your eye pupils are almost closed.Peter</blockquote>
