Hello Pat,
My correction used to be -7.5, but it is now -4.5, so I can use some binoculars without my glasses. However, I find this adequate only in daytime. At night, my astigmatism becomes far more evident. I hope that your eyes are fairly well matched. Mine differ by only a half dioptre.
Really old individual focussing binoculars did accommodate my -7.5 correction. I am writing of 1917-1934 military binoculars. The Swiss Army binoculars of those years were meant to accommodate even rather myopic reservists. As I recall my 7x42 Zeiss Dialyt classic, just managed to allow me to come to infinity. I have a Leica BA, which almost focusses at infinity without my specs: it works at 100m but not on Mars. Try either one to see if it works for you, but do not buy one on my speculation. I consider both binoculars only a little behind the times.
One remedy, which I would not recommend on an expensive binocular, is to get a plastic negative lens, of the proper dioptre or even weaker, and glue it to the binocular at the objectives. Even worse would be to glue it to the objective itself. The former would mar the surface, the latter would entail permanent damage.
Another remedy is to get an optical technician to customise the focussing. Then you gain focussing at infinity but lose some near focussing. Perhaps a first rate manufacturer would do it on a new binocular or allow a special order. I did just that when I sent an eighty year old binocular to a technician for a thorough cleaning, adjustment and collimation. Before the adjustment it barely focussed at infinity; now it has some focussing to spare.
Stay safe,
