I have amblyopia—also known as lazy eye—which means I often see a bit of double vision—usually a sliver duplicated on the outside side of one of my eyes, even when I’m wearing contacts, and even though I don’t look like I have a lazy eye. My eyes definitely don’t work in concert and I’m told my 3D vision resembles what people see when they look at a postcard.
Finally, when I use binoculars, I use only one eyehole up to the non-lazy eye… So I’m wondering what exactly you normal people see out of binoculars? Is it like Looney Tunes?
So… I don’t know about with amblyopia….
But binoculars have an adjustment that brings the view through the two scopes together. If you see two circles (or two overlapping circles), you should adjust it.
