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.
