According to the latest study, one in three children suffers from myopia or "cannot see things clearly in the distance."
Researchers say this global concern is growing, with millions more children expected to be affected by 2050. Children's vision has deteriorated significantly, especially after the pandemic.
The Covid-19 period had a very negative impact on children as they spent a lot of time in front of screens. The highest rates of myopia occur in Asia, 85% of children in Japan and 73% in South Korea. While in China and Russia 40% of children wear glasses.
The lowest rates of this problem are in the United Kingdom, Ireland, Paraguay and Uganda. The study, published in the British Journal of Ophthalmology, reviewed research involving more than 5 million children and adolescents from 50 countries on six continents. From 6 to 1990, myopia increased by 2023%.
There are factors that make it much more likely, such as genetics when children inherit it from their parents. But in most cases it is related to exposure to phone, computer or television screens.
What are the signs of myopia?
-Difficulty reading words from a distance, such as reading the whiteboard at school.
-Sitting near the TV or computer, or holding a cell phone or tablet too close to your face
-Headache
-Frequent rubbing of the eyes
