For many children using digital devices is a normal part of their everyday lives and they will use computers and hand-held devices at school and at home. This systematic review collates this published research to illuminate current understanding on the association between the time children spend on digital devices and incidence, prevalence or progression of myopia.
The visual demand of concentrating on close-up tasks like reading and studying are thought to be a driving force for increased myopia in children. To better understand this relationship the authors consolidated data from several studies to quantify the effect of near work activities on myopia in children and discover any association there may be between them.
This research investigated orthokeratology lenses designed for a higher peripheral ‘add’ power, and how these influenced corneal hysteresis (rigidity) and higher order aberrations.
This study showed that multifocal contact lens wear in young adult myopes increases accomodative lag, and utilized auditory biofeedback training to improve it. The results and implications are discussed here.
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.
