As a strabismic figuring out how to get her eyes to work together in her 40s… I think a lot of people don’t realise you’ve got little muscles that rotate your eyes.
And normally those muscles are nicely synchronised. Your eyes rotate together. If they aren’t, you get two images that are rotated relative to each other. This can be very annoying.
Mine are… intermittently synchronised. And apparently this is something at least partially / sometimes under my control. It’s particularly unpleasant with text. Imagine you have two images of the same line of text, and they’re subjectively in the same place… but the one from your left eye is rotated about 15 degrees clockwise relative to the image from your right eye. What you’re seeing is more like a flattened “x” than a horizontal line.
I haven’t seen anyone else mention this shit. Material on figuring out binocular vision as an adult is thin on the ground as it is, but rotation issues are really flying under the radar.
Also I’m wondering if this plays a role in dyslexia. ‘Cause, yeah, it can make reading very visually confusing. And how often is anyone even checking kids who have trouble reading for cyclotropia?
