How Screen Time is Shaping the Future of Eye Health

Content Blog - Myopia Screen Time

Screen time has a significant impact on myopia rates, especially among children and adolescents. Here are some key points:

  1. Increased Risk: Studies have shown that each additional hour can increase the odds of developing myopia by approximately 21%. This risk is even higher when it exceeds four hours a day
  2. Type of Screen Use: Different types of screen use have varying impacts. For instance, screen time from computers and televisions is more strongly associated with myopia compared to smartphone use
  3. Dose-Response Relationship: The relationship between screen usage and myopia follows a dose-response pattern. The risk increases significantly with 1-4 hours of daily usage and then rises more gradually beyond that
  4. Reduced Outdoor Time: Increased in screen usage often correlates with reduced outdoor activities, which is another contributing factor to the rise in myopia. Outdoor exposure is beneficial for eye health and can help mitigate the risk of myopia

Managing all this and encouraging outdoor activities are crucial steps in reducing the risk of myopia, especially for younger individuals.
