TFT screen basically does not cause too much damage to the eyes. Compared to CRT (cathode ray tube) screens, TFT screens use LED or fluorescent tube back light technology, which produces far less ultraviolet light and radiation than CRT screens.
However, with excessive use of any screen, there is a risk of eye strain and visual stress. Therefore, in order to protect eye health, you need to pay attention to proper rest, avoid staring at the computer screen for a long time, blink frequently, adjust the brightness and contrast of the monitor, etc.
