Hello folks,
I have started doing binocular viewing again, after not having done it for a year or two. One of the things I realized was just how useless my non dominant eye was. For example, just reading black on white text on a computer monitor, things seem dimmer and there seem to be blind spots everywhere. Now I know that eyes have a literal blind spot that your brain fills in thru some kind of compensation / fake image processing. It feels fully working for my right eye and shut off for my left. In the astronomical sense, when I alternately shut one eye to do focusing on a medium-brightness star, it works fine for the right eye even though the star drifts around due to the binoculars being hand held But for the left eye the star seems to fade in and out.
When doing two-eyed viewing, I still have to do the "merge images" thing, and then the viewing does become very relaxed and immersive. But again, it feels like my brain is just using the left eye data for support and discarding it if anything is wrong. e.g. when the left exit pupil drifts off, I don't really seem to notice it.
Anyway, I doubt there is anything wrong physically with my eyes as my last exam from 2 years ago came out ok - it just feels like the image processing algorithms aren't being used on the left. Would it help to do eyepiece viewing with the left eye for "practice"? Or just spend some time (at home) walking around with an eyepatch?
