Large difference in astigmatism between my eyes — could this cause aniseikonia / image rotation?
I’m 45 and I’ve recently started wearing glasses full-time after 25 years of not wearing glasses.
I have a pretty large difference between my two eyes, especially in astigmatism. I’ve attached a photo of my prescription.
My right eye is around -1.00 sphere with -0.75 cylinder, while my left eye has no significant sphere correction but has -3.00 cylinder.
With the new glasses I see very clearly with both eyes, including the left eye. However, I’ve noticed something strange when looking at myself in a small mirror or at my phone/camera.
When I have both eyes open for a while, the image sometimes feels as if the phone/mirror is slightly rotated to the left around its vertical axis, almost as if I were holding the phone slightly turned, even though I know I’m holding it straight.
I do not have double vision, dizziness, headaches or problems walking/driving. In normal situations (driving, walking outside, supermarket, etc.) I don't notice anything looking crooked. It’s mainly noticeable when I specifically look at a mirror/phone and pay attention to it.
Interestingly, if I cover one eye, I don't really notice the effect. It seems to happen mainly when both eyes are open and the brain combines the two images.
I’m wondering whether this could be related to aniseikonia or binocular adaptation, given the large difference in astigmatism between my eyes, or whether I should have the lenses checked for cylinder axis/centration.
I’m currently in my second week of adaptation to the new glasses.
Fitting is double checked and boost zone in the bottom is centered properly in front of me.
Has anyone here had a similar experience with a large difference in astigmatism between the two eyes? I’d particularly like to hear from optometrists/opticians or people with similar prescriptions.
What would you check first: adaptation, aniseikonia/binocular vision, or the actual lens axis/centration?
