Rules for smartphone usage among children

What happened to these children during lockdown?

Why, the very thing that has been a difference with everyone’s life in lockdown: Rules for smartphone usage among children

long, extended hours of uninterrupted screen time became far more common, while outdoor time became increasingly scarce.

Few children received even one hour of outdoor time after the outbreak of COVID 19, while even fewer were able to get the recommended two hours.

While all children showed an increase in screen time, among those children who were already myopic, the increase was substantially greater. ลาวสามัคคี วีไอพี

 Interestingly, the type of screen being viewed during screen time has a big effect on myopia as well.

Smartphones and tablets are the most common types of screens which children are likely to use, and also potentially the most damaging.

A sophisticated study conducted among Dutch teenagers used a background app on their smartphones,

which measured all aspects of use, including light circumstances, reading distance, and the clarity of their screens.

This study revealed that a high number of cell phone use in over 20 minutes had a direct correlation to axial length.

Similar studies on desktop computers showed substantially less correlation between myopia

and screen time. In fact, the desktop screens demonstrated less correlation than reading a book.

Dr. Klaver recommended a series of rules for smartphone use among young people, in line with WHO guidelines.

Children under the age of two should not be exposed to them at all, while those from ages two to five should have under an hour of screen time each day.

For children between six and 10, less than two hours per day is recommended, while from 10 to 15, less than three hours is suggested. For both of those groups, however,

breaks are strongly recommended every 20 minutes. The dangers of blue light Later in the session,

Dr. Cécile Delcourt expounded on the dangers of screen time by presenting the impact of blue light on eye health.

Blue light corresponds to the shorter wavelengths of the visible spectrum and is therefore of higher energy intensity than other colors.

While more intense, invisible light such as ultraviolet light is absorbed largely

by the cornea and the lens, blue light is the most energetic part of the light which is absorbed primarily by the retina.
