How to protect the eyes of children from overexposure to screens?

Tablets at school

For the new school year, the Digital Plan for Education, introduced in 2015, plans to include in the program of 27 academies the use of digital tablets. Doctors and opticians warn parents about the harmful effects of prolonged exposure to the eyes of children, who are already very used to screens.

By 2017, about 600,000 pupils will have “mobile individual equipment”. By 2016, only 200,000 schoolchildren benefited from it in 1,817 schools and 1,668 colleges.

According to a survey carried out in June 2016 by the Research Center for the Study and Observation of Living Conditions (Credoc), every week schoolchildren (12-17 years) devote more than 42 hours of their time to the screens. Doctors recommend that parents introduce rules to reduce the impact of blue light from tablets, computers, mobile phones and even light bulbs in homes. In the short term, the blue light dries up the eyeball and tires the eyes. In the long term, it increases the chance of developing age-related macular degeneration (AMD).

In addition to its consequences on the eyes, this blue light upsets sleep because it slows down the secretion of melatonin (the hormone of somnolence) that theoretically releases in the body around 9 pm. The repercussions of a sleep deficiency may result in a decline in academic performance, although the first results following the introduction of the tablets indicate an improvement in student motivation.

Decrease blue light to protect eyes

To protect children’s eyes from blue light, it is advisable to activate the “Reduce blue light” option in the settings of computers, tablets and telephones and to enlarge the size of the font. For more advice, it is recommended to consult a specialist. Some opticians offer specific corrections and glasses that protect young people under the age of 16 from the effects of blue light.

Preserving the Retina from Dry Eye

To limit the dryness and fatigue of the eyes, doctors recommend fixing for a few seconds an object or a wall, which does not diffuse blue light. Another exercise: turning your eyes away from your screen every 20 minutes, and fix an item placed at least 6 meters away. A repeated blinking of the eyelids promotes hydration of the eyes.

Practicing more outdoor activities

To rest the eyes of the exposure to the screens, it is necessary to multiply the outings outdoors. Sunlight is very beneficial.
