The contrast theory in myopia development and control is based on links between retinal cone expressions, genetics and myopia. This is distinct from peripheral defocus and simultaneous defocus theories and underpins the new SightGlass DOT 0.2 spectacle lens for myopia control. Learn more here.
Digital eye strain is becoming more common in children and teenagers. The symptoms of asthenopia can be due to dry eye, binocular vision dysfunction and glare sensitivity – learn more about each of these, as well as guidelines to manage the risks.
A dose-response is where an increasing amount of a medication or intervention is correlated with a better clinical outcome. When it comes to myopia control, we investigate the evidence for a dose-response with spectacle, contact lens, atropine and outdoor time interventions.
The COVID-19 pandemic saw widespread home confinement, increased screen time in children with home-based learning, and decreased time spent outdoors. Several recent publications have explored the impact of this period of time on the incidence and progression of myopia, lifestyle behaviours, digital eye strain, myopia treatment efficacy and more. What should we now monitor and discuss with our young myopic patients in the post-COVID world?
Adults with myopia may not understand that they have more than just a problem seeing clearly. We discuss genetic risk in glaucoma and macular degeneration – are you doing the same for myopia? How can we talk to myopic adults about risks for their children and support them to take action?
Will China’s new regulations restricting online gaming in children reduce the myopia crisis? Is there evidence that less screen time increases outdoor time? We explore the links and impacts, positive effects of gaming and advice for parents.
The simplest lifestyle intervention we can advise for both our at-risk pre-myopes and myopia development is to spend more time outdoors.
Children are accessing screens at school, around the home and for personal entertainment at younger and younger ages. At the same time, there has been an unprecedented increase in myopia in children, with higher numbers and earlier age of onset. Read about what we do and don’t know about this link; the impact of screen time on binocular vision and dry eye in kids, and guidelines for advice to parents.
As technology evolves the next big change is likely to be Virtual Reality. Could we expect Virtual Reality to be better for myopia than our screens and smartphones of today? How will the artificially simulated visual environment of VR impact on children’s visual development? Let’s explore what we know and what we’re yet to learn.
