Beware! Excessive use of smartphones can destroy your child's eyesight
Blue light from the smartphones and tablets is long known to have a damaging effect on eyes. Various studies in the past have highlighted the extent of damage that prolonged exposure to the smartphone screen causes to eyes. And now, a new study has highlighted just how much damage exposure to the smartphone screen causes to the kids' eyes.
Japan's Ministry of Education, Culture, Sports, Science and Technology recently conducted a survey to study the visual acuity among the country's youth. The ministry, in its survey conducted between April and June among the school students this year, shed light on some startling trend among the Japanese youth. As per the ministry's findings, a whopping 25.3 per cent of the 3.4 million students in the country were below the 1.0 mark, which is equivalent to 6/6 vision.
To put it simply, over 25 per cent school students in the country don't have the perfect vision, Sora News 24 reported.
What's worse, nearly 34.1 per cent of the elementary school students and nearly 67.09 per cent of the high school students in the country didn't have the perfect vision, which as per the publication is the highest in the Japanese history. The only reassuring news came from the junior high school students who traced a near identical graph for visual acuity this year, with 56.04 per cent student falling short of the perfect vision, compared to last year (56.33 per cent).
Experts have linked these worrisome trends with the increased time spent at staring at the screen while using smartphones and playing mobile games.
Japan has the third largest gaming market in the world with 41 per cent men and 32 per cent women accessing games via their smartphones. These statistics stand in line with the findings by the Japanese ministry. Even so, it is worth noting that staring at the smartphone screen for long durations doesn't necessarily destroy the eyesight.
A 2017 study found that the longer screen time could cause fatigue, dry-eye disease and a condition called computer vision syndrome, which is a condition wherein there is a significant discomfort in the eyes owing to viewing computer or smartphone screen for a long duration.
