Ocular Torsion vision simulator

I made these images to show my doctors how I’ve seen things since my surgery (bilateral lateral rectus recession in May of 2005). I’m hoping these illustrations will help them to help me. The images below are not exact of what I see, but best I could do with my graphic software.
Shower faucet
When I cover my right eye, my left eye sees a distorted view. Amazingly, unless I am very tired, I am able to merge these two together into an image that is fuzzy, but fairly good.
Hairspray
When I relax my eyes and allow them to drift normally, the images split into a “V.” The left image (which normally crosses over to the right side) is a little higher, more transparent, and blurry.
Picture frame
These views of a picture frame show what I see as I look at a picture on the wall with first one eye covered, then the other. I tried to place each image here as they overlapped on the wall.
It’s normal to see a slightly different view with the left and right eyes. This enables stereo or 3-d vision. But the images should be parallel and even in height. For an excellent explanation and illustrations of normal stereo vision, see vision3d.com.
Even when I manage to merge the images into one, I am always aware that my eyes are seeing two different images. My vision and balance feel lopsided. It is very hard to explain this sensation.
I’ve learned to adapt to all this. But I have not given up on the idea that some day maybe I’ll have more surgery to try to correct the problems in my left eye.
