I've never seen a blond bat. Maybe I need new glasses.
Sure you have, remember "Ace Ventura - When Nature Calls" (1995)
That's why the internets are here.
That’s what I keep telling my wife, but at 3am, she's having none of it.
I had the same problem. Nearsighted, but lenses fit for 20/20 still required the use of reading glasses, which I despise.
I find this to be the ironic part of RF photography. Many of us have returned to or lately discovered the joy of rangefinders and in particular older cameras with tiny viewfinders, at a stage of life that demands dual corrected vision. It's sort of a mean trickster, life is.
By-the-by, to learn which eye is dominate, stretch out your arms and hold your hands up, palms forward as if pushing something away.
Bring your hands together until they form a single, small opening/hole between the thumbs and fingers. Focus with both eyes on something in the distance through the opening.
At moderate speed, draw your hands to your face without trying to control anything, still focused on the distant object. You will find that your hands will naturally go to the dominate eye as you continue to view your point-of-focus.
This is a rifleman’s trick that works well when helping new/young shooters starting out.
Cheers
