I am a 56 year old male. About 3 years ago I had a procedure to correct for strabismus. After the procedure I noticed that my vision did not align vertically (rotationally?) between my eyes. With the right eye only, when I look at a level reference, then open my left eye while closing the right, I have to tilt my head several degrees to obtain the same reference. At times my eyes become very tired and I have to cover one of them to continue working on my computer. What options are available for correcting this?
Thank you.
