I wear eyeglasses only art of the time, and rarely with binoculars. But I was curious with what people have done with those screw in pieces that are supposed to help with glasses users. In my Minolta pair, they are useless, as the field of view is really small with glasses. SO I take the glases off and screw the eye pieces all the way out. But as these are x25 binoculars, it seems like the all the way out position cuts down on your field off view. So I screw them back in, and now I get the full view without glasses.
Are these devices ever correct under any use? Seems like I could do without them. In 8x40 or 8x50 sizes, as I have tried at a store, they seem to work better.
I can see some day needing these, so I want them to work both ways!
They do work good with 8x40s. Even with my 8x32, screwing the cups in makes the image better. And it's a lot easier than having to take glasses off every time the binoculars are used.
Oops, meant to say
So I screw them HALF WAY back in, and now I get the full view without glasses.
It seems that the bigger the (binocular) pupil the better glasses work.
