A recent survey conducted by Japan showed that the number of students with imperfect vision is at an all-time high. The survey found that 25.3% of 3.4 million students it tested did not have 20/20 vision. The government attributes this to smartphone usage and mobile games.
“According to experts, this can be linked to the increased time spent staring at screens caused by smartphone usage and mobile games,” said the Japanese Ministry of Education, Culture, Sports, Science, and Technology. This comes after China’s education ministry has indicated that it wants to regulate online gaming, including, the number of games and new releases.
Prior research on smartphone usage in children has shown an increased risk of pediatric dry eye disease. Research has also shown increased incidents of “irritated or burning eyes” and “dry eyes when reading from a smartphone. Research from Cleveland Clinic has shown that high screen time can slow your child’s development and lead to children having fewer friends, relationship trouble, and lower self-esteem.
The US National Institute of Health recommends that children below 2 years of age should have no screen time and screen time should be limited to 1 to 2 hours a day for children over age 2.
