Fantastic 3D Image!

I just found an amazing 3D image. 
For those of you like me who have Strabismus you'll find this fun watch and see what seeing in 3D must look like. If however you already have stereo-vision, but curious what seeing monocularly would be like, then imagine comparing this image with one that does not move, which would make it FLAT! Check it out here and let me know what you think. I do not see the world this way, the way I see is more like it looking at a photo; things are not in 'succession' like they are in this clip, but more lined up along a flat plane.  Imagine seeing the world like this for the first time!  Well, that is what I am learning to do and it is a lot like being an alien and visiting a new planet! Do you see how the tree is in front of the bridge?  Imagine knowing that the tree was in front of the bridge intellectually (as you would in a photograph) but never actually seeing it in front of the bridge!

Sue Barry's Blog in Psychology Today

Quick post!
Check out Sue Barry's Blog Eyes on the Brain in Psychology Today.
I am excited to report that Sue mentions the experience I had the first time I 'felt' my eyes being used at the same time when I fused two images together.  You can read it here.
Sue was the reason I started Vision Therapy in the first place and without her it is likely that learning to see in 3D would never have happened to me!  

More Coffee Babe?

     This past Sunday my husband Sean and I went to the gym and did a double spin class. As we drove home we were starving, so we stopped at a local diner.  
 "I'll have French toast and a side of scrambled eggs," I said to the waitress who came to take our order.  As she lifted the laminated menus she replied, "Oh honey, that's on the specials menu," pointing to the list. 
"Oh," I said, "I didn't see it." 
Just before she turned, steaming pot of coffee in her hand, she said, 
"Oh, that's alright hun, my niece has that same lazy eye."  
Half stunned I said, "Oh, really?" 
"Yea, it runs in my family and she don't see so well either...I noticed right when you sat down that you got that lazy eye too..." 
I just smiled and said, "Yea, I got it."    
     When she walked away, my husband and I looked across the formica table at each other.  We sat there quietly for a few seconds. I decided not to mention it, but then changed my mind.  "Did she really just say that...?" I asked him, to which he nodded yes.  Then we both started to laugh.  
     Most people, like our waitress, still think Strabismus is caused by weak eye muscles, but in most cases the muscles of the eyes work just fine, the problem is in the part of the brain that controls fusion.  "Lazy Eye" and Strabismus are not the same condition
Strabismus is a visual impairment where the two eyes point in different directions. Like mine, one goes up and the other looks down.  The correct layman's term for Strabismus would be "crossed eye",  "wall eye", or "wandering eye".  In my case after three surgeries, I now have hypertropia and hypotropia with a bit of esotropia!  You can see the diagram above for explanations of this.
