Outdoor activities decrease, the time spent in front of the smartphone increases, and myopia also increases.

According to the results of research reported by the American science and culture portal ‘Studyfinds’, it is estimated that if the current increase continues, half of the world’s population will need corrective lenses to eliminate myopia by 2050.
The researchers put a small helmet on a chick. The helmet lenses were adjusted to cover the chick’s eyes and affect the quality of the chick’s vision.
The research results showed that, as in humans, when visual input is distorted, the chicks’ eyes widen and become short-sighted. As the eyes got bigger, a blurriness occurred, which caused the eyes to get even bigger.
Other studies of children and parents have found that a significant cause of increased myopia is that people spend more time focusing on the things in front of them, such as screens, books and computers. The researchers said: “As we spend more time looking at smartphone screens, our eyes start to hurt, but even valuable activities like reading a good book can affect our vision.”
A study published in 2022 found that children who did not spend much time outdoors (once or twice a week) had a rate of myopia more than four times higher than children who were outdoors every day. Furthermore, children who read books or looked at the Internet screen for more than 3 hours a day were four times more likely to develop myopia than children who read books or looked at the Internet screen for less than an hour a day.
Another study, a meta-analysis of seven studies comparing time spent outdoors and the incidence of myopia, found that the more time spent outdoors, the lower the incidence and progression of myopia. Consequently, these studies suggest that time spent on outdoor activities should be increased and that early education should be modified to reduce the incidence of myopia.
The progression of myopia can be stopped by wearing glasses or contact lenses that correct the blurry image for just a few minutes a day. Therefore, early eye tests and vision correction are important.
But the best and safest way is to spend less time focusing on objects close to your face, like books or smartphones, and spend more time under bright natural light.
