About these Meade binoculars....

I'm crossposting this to uk.sci.astronomy and uk.rec.birdwatching since
these binoculars have been discussed on both groups, hope that is OK with
everyone.

I bought two pairs of these binoculars this morning and I have a slight
problem with them. I am just about to research this on the net but I doubt
these are the only binoculars which cause this issue, just the first I've
come across and I'm sure I'm not the only person affected, so I thought it
worth posting.

I am very short-sighted, -8.5, -9. I know very little about optics but I
have two other binoculars and a telescope and have used microscopes,
rifle-scopes, sights on engineers levels etc. On all of these I can focus
both with and without my glasses. I usually prefer to take the glasses off,
I get a clearer focus and avoid light getting in at the sides of the
eyepieces. If using bins with the family I tend to leave my glasses on,
makes it easier for passing them round etc, we don't have to re-focus so
much and since they all have very good vision we don't usually worry about
the left/right eye difference adjustment. For this purpose, which is mainly
why I bought these two pairs, they are excellent. But..... I am completely
unable to focus these with my glasses off at a distance greater than about
30m. Have rtfm, which talks about how to use them with glasses, but as far
as I can see (it's all in French) it doesn't explain if it is possible to
use them without the glasses.

Does anyone else have the same experience with these or other binoculars
with similar magnification, or please could someone explain whether this is
normal and why it happens?
