Hi Geoff,
To be blunt, yes and no. I found that I have to put my eye pretty close to the Dioptrx to take in all of the field and noticed eyelash marks on the surface later. The Dioptrx eyelens is larger than the EP eyelens and is placed very close to it. As it was pretty cold this morning the eye lens on the Dioptrx tended to fog up owing to the warmth of my face. I mentioned earlier that you have to move/roll your eye around the field to take it all in. In any case the benefit to me me by not wearing glasses has been enormous.
As an aside and for others who may be interested, I have a TV 15mm Panoptic which , if used with my TV 2.5X Powermate, doesn't require the use of glasses, it is perfectly sharp and clear. Apparently it all has to do with your exit pupil. Around 1 - 1.5mm is sufficient not to require glasses and astigmatism doesn't come into it. Of course, using the EP by itself, glasses need to be worn.
Hope this answers your question. I realise that it would be a costly outlay if the set up didn't work for you.
Cheers,
Steve
