The Claim

In pre-myopic children aged 6–10 years with spherical equivalent refractive error between +0.75 D and -0.50 D, daily use of distant-image screen technology for at least one hour during near work is associated with a lower probability of myopia onset over one year compared to unmodified near work, with an estimated incidence reduction from 54% in controls to 21% in the intervention group.

Support is ahead, but a single strong opposing study can change this.

In plain English

Children aged 6 to 10 with mild refractive error who use distant-image screen technology for at least one hour per day during near work have a 21% rate of myopia onset after one year, compared to a 54% rate in children who do not use this technology.

See the scientific wording

In pre-myopic children aged 6–10 years with spherical equivalent refractive error between +0.75 D and -0.50 D, daily use of distant-image screen technology for at least one hour during near work is associated with a lower probability of myopia onset over one year compared to unmodified near work, with an estimated incidence reduction from 54% in controls to 21% in the intervention group.

Why this might work

When a child looks at a screen that makes close-up text appear far away, the eyes don't have to strain to focus. This reduces a type of blur on the back of the eye that normally tells the eye to grow longer. With less blur, the eye stops growing too fast, preventing it from becoming nearsighted.

  1. Study: Effect of distant-image screen technology (DIST) on delaying myopia onset in pre-myopia children: study protocol for a1-year randomized controlled trial

    Kids who used a special screen that makes things look far away while reading or doing homework were much less likely to become nearsighted in a year than kids who used regular screens or books.
