“The Scarcity Trap: Why We Keep Digging When We’re Stuck In A Hole”

Here's an interesting NPR podcast about the psychological "scarcity trap": http://www.npr.org/2017/03/20/520587241/the-scarcity-trap-why-we-keep-digging-when-were-stuck-in-a-hole. When you're in need of something, your mind is enveloped by a kind of "tunnel vision" prompting you to solve short term problems in ways that are detrimental to long term success. This can apply to food, money, social contact, time, ... I personally have most experience with this issue in terms of functional vision skills scarcity. My underdeveloped binocular vision makes it harder to accomplish certain tasks so historically I used to double down on my cumbersome strabismic vision habits in order to solve…Read more …

“Our senses can’t learn under stress”

Having compromised sensory abilities can be very stressful and that in turn can impede rehabilitation or further development. Creating a climate of understanding conducive to sensory learning is thus of paramount importance. Read the entire article at: http://neurosciencenews.com/stress-learning-senses-5942/ "Stress is part of our everyday lives – while some thrive on it, it makes others sick. But what does stress do to our senses? When we train them, we can sharpen our senses thereby improve our perceptual performance. The stress hormone cortisol completely blocks this important ability. In the current issue of “Psychoneuroendocrinology” neuroscientists of…Read more …
The Hess Test: How does it work and why is it administered?

The Hess Test: How does it work and why is it administered?

The Hess Test involves anaglyph glasses and a grid attached to a wall or screen in front of the patient. The purpose of this test is to get an idea of whether or not the eyes align absent of any exterior reference points and thus without any compensation ability the patient might usually be employing. During the test the patient is wearing anaglyph glasses while watching the grid. Somewhere within the grid a red light will illuminate itself or will be projected by the clinical assistent. The patient has a green laser pointer…Read more …
Book Review: Vision Rehabilitation: Multidisciplinary Care of the Patient Following Brain Injury

Book Review: Vision Rehabilitation: Multidisciplinary Care of the Patient Following Brain Injury

Throughout 2014, I read a vision care manual called "Vision rehabilitation: Multidisciplinary Care of the Patient Following Brain Injury ". It was an amazing experience. For people with binocular vision problems, or neurological vision issues more generally, the world can be very lonely and hostile as the vast majority of health care practicioners, including most ophthlamologists and neurologists, don't really understand these conditions and don't know how to connect the outwardly visible signs, anatomy and symptoms. Consequently they  know even less about  treating the root of these problems in a constructive manner and…Read more …
Visual discomfort, muscle tension and stretching

Visual discomfort, muscle tension and stretching

There is a persistent problem when doing interactive and, in particular, fine oculo-motor tasks. These tasks include almost everything, from reading, driving, to social interaction, except watching a movie or staring at a blank wall during which you can just let the images wash over you without feeling the necessity to react in a specific oculo-motor way. Even when reading with audio support from audio books, it can get somewhat uncomfortable. After a while my body feels stress, discomfort, agitation. Muscle tense up and pain creeps in. Ultimately I start sweating and experiencing…Read more …
The vestibular system and vision

The vestibular system and vision

I've been reading up on the link between vision and the vestibular system. It's been quite instructive to say the least. Of course it's annoying not to be able to align the eyes and have double vision while reading etc... However, there's more. It's very interesting how compromised eye movements, in large part due to eye muscle surgery, and consequently a compromised Vestibulo-Ocular Reflex are likely to be the biggest source of disability and fatigue for me personally. When going beyond my relatively low visual endurance limit, the sensory conflict between the visual…Read more …
Strabismus, visual field loss and visual-spatial neglect

Strabismus, visual field loss and visual-spatial neglect

"Right after I lost vision in my eye, I was so bad at walking that I ran into a girl eating ice cream, and knocked her cone out of her hand. She screamed: ‘Are you blind!?!?’ I turned to her and said: ‘I am blind actually, I’m so sorry, I’ll buy you a new cone.’ And she said: ‘Oh my God! I’m so sorry! Don’t worry! It’s no problem at all! I’ll buy another one.’ So we walked into the ice cream store together, and the clerk said: ‘I heard the whole thing.…Read more …
Head rotations, bar reading and bring on the prism flippers

Head rotations, bar reading and bring on the prism flippers

  Head rotations Last week, for the first time, I had a completely stable percept while doing my head turns. I couldn't believe it!  I thought I was suppressing or something but I wasn't. Both eyes were just heedlessly adjusting to the head movements without error. It must be great to be able to take these reflexes for granted! I had predicted this milestone for the end of April et voila. Another hurdle taken. The reflexes are not equally reliable every day but that, again, is a matter of time. Speaking of head…Read more …
Hidden treasures

Hidden treasures

During my Uni days I lived with a great guy named Dennis. As a child Dennis had gone through Vision Therapy. There are all levels of irony attached to this fact because I underwent the damaging surgeries while living with someone who already experienced the solution to the problem. Apparently we both didn't connect the dots and when looking for counsel from the 'crème de la crème' of Belgian strabology, I bought into the whole 'It's too late, bring out the knives' story I'd been served again and again. We'd never really talked…Read more …
Vision Therapy and tDCS (2): How and what?

Vision Therapy and tDCS (2): How and what?

First of all I want to thank my buddy Andrew for blazing this trail. I knew about TMS and tDCS but I was not planning on trying it myself anytime soon. That was until he figured out what supplies were needed and had successfully tried it on himself with promising results. I'd like to refer to some of his blog entries to get you more acquinted with his DIY vision therapy tDCS adventures. - http://vtwithsyntonics.blogspot.be/2013/11/167-session-tdcs-with-syntonics.html - http://vtwithsyntonics.blogspot.be/2013/12/170-session-tdcs-works-very-well.html - http://vtwithsyntonics.blogspot.be/2013/12/reddit-discussion.html - http://vtwithsyntonics.blogspot.be/2013/12/174-session-sensory-fusion-driving.html - http://vtwithsyntonics.blogspot.be/2013/12/178-session-what-tdcs-seems-to-do.html He even made a video tutorial breaking down what's involved in setting up tDCS.
