In addition, the constant screen jitter of the computer screen also affects the focusing frequency of the glasses, and the repeated focusing caused by this jitter also aggravates the eyes' fatigue. According to a report by Japan’s NHK, a survey shows that blue light from LCD screens such as computers and smart phones may cause eye fatigue, disrupt sleep rhythm, and affect health. Most of the LCD screens emitted from computers, smart phones, and tablet terminals emit blue light. More and more people use these devices for a long period of time. Doctors are worried about the possible health effects.
