As a birder for more than 30 years I have lots of experience with binoculars, but three major retinal surgeries last year created a problem. None of my current binoculars work satisfactorily anymore, so I'm seeking advice from others--especially if you have similar difficulties. Here's what you need to know:
--I've always been extremely nearsighted in both eyes and have worn spectacles since childhood.
--I had three surgeries for a retinal tear in my left eye.
--Due to the surgeries, I developed a cataract in my left eye and had to have a lens implant that essentially corrected my nearsightedness in that eye.
--I still have astigmatism in my left eye, which means I still have to have a corrective spectacle lens; thus I wear glasses that include a corrective lens for each eye.
--Because the left and right eyes are now very different, the spectacle lenses are also very different--so different that the various binocs I have can't be adjusted far enough to accommodate both eyes. (In other words, even when I focus for one eye with the thumb focus, I can't turn the adjustable eyepiece far enough for BOTH eyes to be in focus.)
Can anyone suggest any good quality 8X or 10X binoculars that can be adjusted enough to solve my problem?
Thanks in advance,
BILL
On a similar post a day or so ago, Otto Mc D. mentioned he "adjusted" the IF of the right eye of a bin to extend the diopters available. He mentioned doing it with a knife blade. Maybe he could elaborate on that here. It might solve your problem.

You need a pair of IF (individual focus) binoculars which have as much adjustment as possible for each eye (-5/+5). Try to find some in 7x50 or 8x30.
Check Fujinon 8x30 FMTR-SX at Eagle Optics (you can send them back if they don't work), Steiner, Hensoldt, IOR, and the Russian stuff.
