Advice about binoculars

Hi all,

This is slightly OT as I don`t normally use binoculars for
astronomical purposes, but as I like to view the night sky when I am
on walking holidays in the country (waste of time from London), it is
somewhat relevant.

I have been wearing spectacles for about 3 years, I have one
short-sighted eye, the other long-sighted! Trouble is, I find using
binoculars while wearing the specs very difficult, but I have found
that I cannot adjust the left eyepiece enough after focusing the
binoculars whilst looking through the right one, when using the bins
without wearing the specs.

Are there any binoculars available with a wider range of adjustment
for the left eyepiece?

Any advice for this problem gratefully received. I hope I have
explained my problem clearly?

TIA

Larry
