Iv'e noticed that if I I'm careful when taking up the Trinovid to my face the smear is minimal, but if i just by accudent add a bit too much pressure toward my face, the risk of smears increases significantly. I get the impression that I could eliminate the problem with 1-2 millimeters more on the eyecups, not really to increase the distance t the eyes, but rather to have some more stiffnes. But I guess a rolled back 18mm eyecup would be better at this as well.Like you can see on the first picture, the eyecups are pretty old and the top portion is almost at a 30-degree angle. First of all this results in less required force to "squash" the eyecup and bring the ocular lenses closer to my face. Secondly, the angle results in a small but not insignificant loss of distance. I'm wondering if a new set of original 10mm eyecups perhaps is enough for me to eliminate the issue... Although it's probably better do just do like you did and get the extra long ones in order to get some more playroom. -Do you by any chance know if the older style "non-floppy" eyecups (seem to be plastic, or very hard rubber) perhaps do the job better in this case? I would assume they don't deform much, if anything at all.</blockquote>
