Hello Sam, welcome to the forum.
I'm sorry to hear you have a progressive eye problem. It must be a real concern.
Wearing glasses per se, should be no hindrance to using binoculars, but it is an issue which vexes a lot of people. The large majority of binoculars on the market are designed to be eyeglass friendly, but in practice, is does rather depend on you choice of frames, how they are fitted and the strength of your prescription.
The binocular designers set an distance between the lens of the eyepiece and optimal eye position. It is usually referred to as eye relief. If your eye is to close you will experience what we call blackouts. If it is too far away, the effective field of view will get get progressively narrower. With the help of your optician you can estimate your requirements, but most simply resort to trial and error. The best tactic is to visit a specialist shop and find the one that works best. Alternatively some simply look for models with the longest eye relief. In this case you may find you need to twist out the eyecups a few millimetres to avoid blackouts. Models with the longest eye relief may well have a narrower fields of view. The eye relief is usually listed in the binocular specification. Less than 17mm will need fairly close fitting glasses. Most spectacle wearers will find 19mm quite adequate. A few will need 20mm or more. I actually chose close fitting frames for birdwatching to make life a bit easier, but few think that's a worthwhile expense.
You haven't mentioned a budget. You will find quite usable models for less than £100, but if you can, I feel it's worth spending a bit more for better coatings, optical designs and engineering if possible.
I don't know your area at all, but I see Comely Cameras in Cleethorps lists Minox and Opticron models which would be a pretty reasonable place to start.
