Book Review: ‘The hidden link between vision and learning’ by Wendy Beth Rosen

Book Review: ‘The hidden link between vision and learning’ by Wendy Beth Rosen

The author of this book, Wendy Beth Rosen, was so kind to lend me an e-copy of her new book for review. As I love books and am obsessed with vision, I gladly accepted. The book reminded me of a book earlier reviewed on this website: Suddenly Successful by H. Dawkins (1989). That being the case, many of its core points were not all that new to me but they still haven't become any less relevant!  'The hidden link between vision and learning' provides a basic theoretical framework for understanding binocular vision problems and…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 …
Research: The Effects of Sports Vision Training on Binocular Vision Function in Female University Athletes

Research: The Effects of Sports Vision Training on Binocular Vision Function in Female University Athletes

An interesting piece of research, available on the website of the US National Institutes of Health, came to my attention recently. It was published in December, 2015. It is part of a growing body of research validating the efficacy of Vision Training. I'm posting it here because it also includes some practical exercises which might inspire you to try them yourself. If you are a strabismic, make sure the risk of double vision or other adverse side effects is under control by talking to a qualified Behavioral Optometrist.

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 …

Book Review: Dr. B’s Parent and Teacher Guides on Child Vision, Learning & Development: Fundamentals 1

REMINDER: To have the article read to you, select the desired paragraph and click on the little speaker icon. After setting up this new website, I sat down to review Charles Boulet's first 'Parent and Teacher Guide to Child Vision, Learning and Development'. It had been on my to-do list for some time! The text reflects many of my views on what is going wrong during standard vision screenings (especially as far as farsightedness is concerned), binocular vision treatment and, more generally, in how children with sensory-motor difficulties are being treated. These subjects are close to my heart. The…Read more …
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 …
The visual system’s important role in figuring out where you are

The visual system’s important role in figuring out where you are

Developmental strabismics often learn how to suppress sight coming through one eye. Many times they even learn how to alternate between both eyes. This is a useful short term neural adaptation but has many disadvantages in the long haul if not corrected. Having been, and to some extent still being, an alternator, I know how it works in practice and how it feels. If feels like you can shift between two ways of seeing. You are not only switching between your physical eyes but also between two viewing positions in your mind. You…Read more …
Mark B, strabismic pilot with eyes on the skies

Mark B, strabismic pilot with eyes on the skies

Around a year ago I met Mark B. through our DIY Vision Therapy Facebook group. Every so often he'd post a picture of a little airplane or an air field on his Facebook profile. I thought he must really like planes but since he was strabismic he probably doesn't fly them himself. Turns out I was wrong! MICHAEL: Hi Mark, where do you live and how old are you? MARK: I live in the Brittish midlands, in Redditch more specifically. That's just south of Birmingham. I'm 39 years old and will turn 40…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 …
