You know something which fascinates me?
I have a Russian 7X30 binocular. It is the real military model and exceptionally sharp optically. It has a very unusual focusing system. It has individual focusing eye pieces which is not unusual in military binoculars. That is more sturdy and easier to make waterproof.
The unusual thing is that as you focus an eyepiece it has a slight zoom function. If your eyes require different diopter settings, as mine do, then one side will have more magnification than the other.
The amazing thing to me is your brain will combine the two sides into the same magnification without your even knowing.
Amazing thing this human brain, brought to you by evolution over billions of years. /s
Take your glasses off and instant focus when viewed through.
Tested with Mom who wore Coke Bottle glasses at the time and she said they were great
That is called "Focus breathing"
That your brain fixes it doesn't surprise me at all. The left was seeing Russian collusion for 2 years that didn't exist ;)
I was born with 20/400 vision in my right eye so my left eye naturally corrected and I once had 20/18 vision. I can shoot rifles (left handed) and billiards very well as I am right handed, and if I look at objects at just the right angle I get what seems like 3D vision. My one eye sees an object and at the same time my other eye sees the blur of an adjoining object. Hard to describe but unique, I am sure!
