Article title: « Question of the week: are screens bad for the eyes? »
Answer:
Medical research has not found a direct link between screen use and long-term vision damage. However, prolonged screen time can cause digital eye strain, also known as computer vision syndrome. Symptoms include dry eyes, blurred vision, and headaches. To alleviate these symptoms, it is recommended to follow the 20-20-20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away. Adjusting screen brightness, text size, and contrast can also help reduce eye strain. It is important to note that screen time should not replace sleep or physical activity, and children should follow screen time guidelines to promote healthy development.
