Abstract

Shortsightedness is caused by the eye growing too long, which results in faraway objects, such as the board in school, appearing blurry. People who are shortsighted wear glasses or contact lenses to see better. But would not it be incredible to figure out and avoid whatever causes shortsightedness, so we could wave goodbye to our never-clean, always-lost, forever-slipping-down-our-face glasses? Well, scientists have already started to solve the puzzle of shortsightedness and have discovered that time spent doing close-up tasks, such as reading, may put us at risk of shortsightedness. But now there is another near task we must consider, our ground-breaking, picture-taking, TikTok-making smartphones! We therefore carried out the first ever study looking at shortsightedness and smartphone data use and discovered that young people growing up with smartphones appear to be at greater risk of shortsightedness.
