Aperture Rule: A Vision Therapy empathy top tip

Aperture Rule: A Vision Therapy empathy top tip

As you might know, at this point my eyes are looking pretty much normal most of the time but the inability to converge consistently remains crippling. It drains and strains a lot. It's like a massive extra backpack I'm wearing, or an invisible barrier between me and the world, preventing me from getting things done more easily. Currently, much of the time, I'm living with a male cousin named Thierry (22) and female cousin named Cynthia (26). They are very nice about my peculiar situation and try to understand. I, in turn, am…Read more …
Cheiroscope: video, drawing samples and implications

Cheiroscope: video, drawing samples and implications

After a nice theoretical post, let's get down to the nitty gritty. How can we get a tangible look into how someone perceives his personal space? How can we determine inconsistent perception of space interfering with the construction of solid brain maps? As vision writes spatial equations for the muscles to solve, cheiroscopic drawing is an interesting way to gauge the state of ocular motor ability and spatial vision. During cheiroscopic drawing, one's visual system is completely stripped of contextual aids. Broader context often helps strabismics to get around and complete certain tasks…Read more …
“Electronic Rapid Alternate Occlusion Goggles” as Anti-Suppression treatment

“Electronic Rapid Alternate Occlusion Goggles” as Anti-Suppression treatment

Following an interesting thread on Facebook and some e-mailing back and forth with Patricia Simone Fink OD and Eric Hussey OD who were generous enough to share their time, research and experience with me, I decided to make another investment in my vision in the form of Electronic Rapid Alternation Occlusion Goggles. New year, new projects and new ways of approaching existing problems! What are Electronic Rapid Alternate Occlusion Goggles? "Electronic rapid alternate occlusion (ERAO) using liquid crystal lenses is used to treat suppression of binocular vision, a defect affecting the sensory combination…Read more …
Session 80: Large rope circles projected on the wall

Session 80: Large rope circles projected on the wall

After almost four years of me doing Vision Therapy, our VT office finally got around to repairing an old projector they had in storage. It's pretty cool. Now we can finally do polarized quoits vectograms on a bigger scale by projecting them on some kind of grey screen on the wall. My Vision Therapist named Sofie was doing the exercise simultaneously with me. Funnily enough her ocular movement ranges at that distance (2 to 3 meters) were similar to mine. Keeping my circles singled out is going pretty well then but I didn't…Read more …

Session 79: A short Aperture Rule update

Recently a VT friend of mine named Pasquale asked me how I had progressed in executing the Aperture Rule ever since I wrote 'Doing time' two years ago. Last week I asked my Vision Therapist whether I could try the AR again to verify.   Two years ago I only recently started having single vision some of the time. Back then I was able to execute the AR up to level 4 (of a total of 12) both with the exo and eso settings.   Right now I am able to execute the…Read more …
Session 72: In pursuit of more speed, accuracy and consistency

Session 72: In pursuit of more speed, accuracy and consistency

The foundation has been put in place. Finishing it up by perfecting the collaboration between vergence (eye movements) and accommodation (manipulation of the eye lens by your tiny muscles in the eye) and increasing capacity will be the closing deal. Major physical restrictions have been largely eliminated. More speed, more accuracy and more endurance. These will be the stakes as I move towards normal functionality. The time that I could not even participate in certain training activities has passed. Finally most activities are accessible and progress will, rather than being merely damage control and…Read more …
My granddad is a 3D nerd

My granddad is a 3D nerd

Throughout his life my granddad has always been very fond of photography and until this day he tries to keep up with current developments in digital photography. Back in his early days he had one of the first cameras and even one of the first stereocameras. It's safe to say he was an early adopter of the 3D technology back in the fifties. This makes for interesting photos and material. He has this ancient case containing two frame slides with pictures he took during his lifetime. Even pictures of my grand grand father.…Read more …
Cross-eyed 3D photography

Cross-eyed 3D photography

The purpose of this image is to perceive a 3D effect by feeding each eye a different, matching image. In order to make that happen the viewer needs to cross his eyes. If all goes well and you are able to fuse the two images you will see a combination of both images, meaning you will see open space on BOTH sides of the mountain. Possibly you will also perceive a 3D effect. I don't see it yet so I'm not really sure... I can cross my eyes and make it fit, but…Read more …
