Lying down to read or watching the computer, which is more harmful to the eyes?

Lying down to read and watching the computer will cause damage to the eyes, but the degree of damage may be different. When lying down to read, your eyes will be placed parallel to the book, causing your eyeballs to be at the same level for a long time, causing eye muscle fatigue. At the same time, the need to constantly adjust the focus of the eyes to read the text would also cause damage to the eyes. In addition, if you read for a long time, your eyes would be stimulated by the light, causing fatigue and dryness in your eyes. When looking at the computer, one's eyes needed to stare at the screen for a long time, causing eye muscle fatigue. The brightness and contrast of the screen will also affect the comfort of the eyes. If the screen is too bright or too dark, the eyes will feel irritation and discomfort. At the same time, the computer screen was usually larger than the reading screen. The need to constantly adjust the focus to see the screen content could also cause damage to the eyes. Therefore, in order to protect your eyes, it is recommended to take frequent breaks and leave the computer screen for outdoor activities every once in a while. At the same time, keep the brightness and contrast of the screen moderate to avoid excessive stimulation of the eyes.
