@maryb1996 In your description about the cube illusion, and your eyes shifting, I had another thought. Usually we have a dominant eye that does most of our focusing for close work. The brain puts the images together from both eyes for depth perception. What you might be describing is the dominance shifting between your eyes as you look at something. You can cover each eye by itself to figure out which eye is doing the seeing. My eyes don't converge well at close distances, and if I check this, the image from each of my eyes are a distance apart. Sometimes my brain just picks one, and that image can shift back and forth spontaneously, but when I concentrate, my brain ignores one of the images, but I am seeing and comprehending the image correctly. I've always been like this. You could be like this too. You might be having trouble combining images from your eyes. Have you seen an ophthalmologist? It might be a good idea in case there is something in the eye causing the wrong signals to be sent. An ophthalmologist is a medical doctor and an optometrist is not a medical doctor. The ophthalmologist can also write orders for imaging of the brain, and you may get a quicker appointment. The retina has rods and cones that convert the focused image into nerve impulses that are sent through the optic nerves to the brain where the information is processed in the visual cortex. Anything abnormal along that entire pathway can affect vision and processing. The optic nerves are on the underside of the brain and cross over in an "X" to the opposite side of the brain. If there was a mass or tumor putting pressure on the optic nerves, it could also affect the signals that are sent. These would be things that an MRI could show. I'm just thinking outside the box about how this works, so you can ask questions of your providers. I used to work for a neuroanatomist at a university who was mapping the visual system (and studying visual abnormalities) from the retina to the visual cortex.

Amazing insight! again, thank you very much for all the time and effort you are putting in order to provide me with potential answers. I am familiar with most of the things you just said (I am a psychology graduate, currently working under neuropsychologists). It happens that I saw an ophthalmologist frequently in the past period because I had PRK corrective eye surgery. I highly doubt it has anything to do with this, especially since my problems started occurring before the surgery? I am however not sure about your explanation concerning combining the images from the two eyes for stereovision: it makes complete sense but some of the "shifts" I am experiencing are shifts between objects that usually look nothing alike, and that would not explain other symptoms. There is one symptom I completely forgot to mention: I suddenly have problems with speech that do not occur as often. While speaking ordinarily (not under any sort of pressure or stress), I may confuse syllables while speaking, result being I say slurred and meaningless words. While I actively focus on trying to correct my words after having mixed up the syllables the first time, the words still come out wrong, with another completely meaningless combination or order of syllables. I however neglected/forgot about mentioning this in my previous post because it happens less often, yet it is also becoming slowly more frequent. Again, I really appreciate your time, efforts and thoughts 🙂
