I suppose that could be entirely possible due to different variables such as the thickness of the glasses, nose pieces, set of the eyes, etc. As I look back thru some of his posts, I notice that he states his prescription is quite strong, and has made other references to the thickness of his lenses.
You've done some good research there. I probably should have provided a link to the thread I posted to when I tested them:

Posting #6 is after I'd tested the 8x42s
It seems like another reviewer could still use these 8x42's with his sunglasses on and with the eyecups fully extended, based on comments in a previous post.
I find it odd if so few people are finding these ok with glasses. Perhaps I need more relief than most people for some reason. My glasses lenses are thickish at the edges, but because I'm short sighted, they're quite thin in the middle. I wear them back quite a long way, and if I push them back any further my eyelashes touch the glass. Maybe I've got unusually long eyelashes?
I'm certain I had the eyecups all the way in. I wonder if there was something wrong with them. They certainly looked ok and were new out of a box. They had just ordered them in for me to try.
The posting after mine in that thread (#7) mentions "moderate wrap sunglasses" being fine with them. Sunglasses lenses are very thin all the way across, and perhaps the "wrap" style lets you get the eyepieces a mm or two closer.
My comment was in no way meant to disparage the poster, or to imply that he did not see what he reported. I merely made my comments based on my own observations, and others comments so that the OP would not dismiss these out of hand based on one comment. They are very good binos for the $$, and seem to be entirely suitable for the majority of eyeglass users.
No offence taken at all, I'm glad you questioned it. I'd definitely recommend the OP at least try these binoculars. My comment was only a warning not to buy them sight unseen.
I was very disappointed and surprised that I had to reject them for this reason. I'm still perplexed how 17mm of relief wouldn't be enough, when my old Legend 8x42 porros, rated at 15mm, were ok.
Perhaps the 15mm is underrated. The last posting in that thread (#11) describes how to measure the relief for yourself, but I never got around to measuring it on my Legends. I should do that, as it ought to explain this mystery.
