So happy when you are happy!
We just received a lovely feedback from one of our clients today and are delighted to share it with you. It always makes us very proud (and happy of course) when we see that the therapy has yet again shown wonderful results. It amazes us again and again how many of our clients had had their eyes checked before coming to us and 'everything was ok'. One more time a reminder that an eye-check (for acuity / eye-sight) is not the same as a proper assessment for functional vision

The Association between Near Work Activities and Myopia in Children—A Systematic Review and Meta-Ana
This is an amazing study on near work and myopia. In this study, many publications from 1989 to 2014 on the relationship between myopia and prolonged near work were analysed and the results are astonishing… "We found that more time spent on near work activities was associated with higher odds of myopia (odds ratio [OR] = 1.14; 95% confidence interval [CI] = 1.08–1.20) and that the odds of myopia increased by 2% (OR:1.02; 95% CI = 1.01–1.03) for every one diopter-hour (hr) mo

What too much screen time does to the eyes
We just read this article on CBS News . It was originally published in August 2015 but hast not lost any of its relevance - in the contrary... we believe that screen time has even increased since then. This is why we share it with you here, cross-referencing the article to some of our own articles on the blog to give you more insight. And we want to start with the words with which the article closes: "[The computers] are very useful, obviously.... We're not saying don't use

Why is your child closing one eye?
Some parents find it cute when their child closes one eye. Very often, that is not as cute as parents think, as it could be a symptom of strabismus or a lazy eye. By shutting one eye, a child overcomes difficulties to use both eyes together. Frequently, parents ask for help only after a few years when the squint gets much worse. Just recently, I had such a 'case' at Orthovision . After having done all the tests on the boy, I talked to the mother. As I wanted her to understa

What are the primitive reflexes and why do we need them?
Everyone is born with a set of primitive reflexes in order to go through the early years of life , particularly the first year. Primitive reflexes navigate a newborn to look for food (rooting and suck reflexes) or to change the position of the body in order to avoid a danger or to prevent suffocation (Moro & ATNR reflexes). The list of reasons why the primitive reflexes are necessary and essential in the early development is long. You can find more information on the reflexe

A Short Course ... - Lesson 7
Congratulations, we are halfway through our 'course' already! How do you feel? Today, we are focusing on the position of your reading material (and subsequently your posture). Lesson 7: Tilt your book up about 20 degrees (this slopes up about 4 inches in 12). By doing this, you can usually work farther away than when you place the book flat on the desk. I found this picture when I searched for book stands and I think it shows very nicely how your posture changes completely

A Short Course on Visual Hygiene - Lesson 1
Having just returned from an extended time away from the office, it is not just me who feels refreshed - my eyes were on a long holiday, too! We spent only a few minutes a day looking at screens and otherwise enjoyed the scenery and the outdoors of beautiful Switzerland. When I did read some of the books I brought along, I noticed how much difference following the 'rules' makes! Naturally, I did not follow all of them all the time, but my eyes said 'thank you' every time I
