With the development of our society, computers have been integrated into our lives, especially in cities. While computers bring us convenience, they also add risk factors to our glaucoma patients. A study showed that people who face a computer screen for nine hours or more a day, especially those with nearsighted eyes, are twice as likely to develop glaucoma as those with normal vision. The reason for this may be that the optic nerve in eyes that have developed myopia is more susceptible to damage than the optic nerve in normal eyes, and prolonged computer use may be a cause of this damage. Therefore, glaucoma patients must pay attention to eye hygiene because when people read and use computers, a group of small muscles in the eye called ciliary muscles work hard to increase the curvature of our lens so that we can read, write and use computers clearly; if we do not pay attention to eye hygiene, these hard-working ciliary muscles will become more easily fatigued, and at the same time, the curvature of the lens If we do not take care of our eye hygiene, these hard-working ciliary muscles will become more easily fatigued, and at the same time, the curvature of the lens will increase further. Therefore, we are reading, ambulatory work and the use of computers, the placement of the computer screen should be moderate, behind the screen is best to have enough space for the eyes to see far; screen must be clean, and the screen brightness and color contrast to the most comfortable state, so that the eyes are not easy to fatigue; the use of light must be sufficient soft, light must come from both sides, not from the front and back; to adjust the light and people and the book ( or screen) distance; to have the correct posture, do not use your eyes for a long time with your head down, and do not overuse your eyes, read or amble for about an hour should take a break for a moment, for a far view, for those who use computers, about every 20 minutes to let the eyes rest regularly; it is best to leave the seat when taking a break, and carry out appropriate whole body activities; must wear glasses to correct any vision problems, and regular optometry.
