Message: <blockquote data-quote="chill6x6" data-source="post: 3532197" data-attributes="member: 130888">That 15.5mm eye relief is for the Trinovid, not the Trinovid HD.  The Trinovid HD 8X42 is LISTED at 17mm.  The PREVIOUS model Trinovid is listed at 15.5mm.  I have both.  I find the Trinvoid useable, JUST.  The Trinovid HD is much better.  I even have to twist the eyecup out a little.  My responses are in RED.  Eye relief figures are not consistent brand to brand and sometimes WITHIN brands.  Zeiss seems to list 16mm for everything.  You can almost bet if Zeiss list 16mm, it is at LEAST 16mm and more times that not MORE than 16mm and very eye glass friendly.I'm sure it's possible but I can't imagine an eyeglass wearer having an issue with the 8X42 Trinovid HD or the 8X42 MHG since I have to twist the eyecup OUT some.</blockquote>
