As we know, normal human eyes will keep secreting tears, and then by blinking, the tears will be evenly coated on the surface of cornea and conjunctiva, forming a tear film, so it can keep the eyes moist and not dry. However, as most offices are now open to air conditioning and heating, the air is very dry, the tear film is quickly evaporated, our eyes will be very “dehydrated”. Solution: use air humidifier, if possible, you can also put a pot of aquatic plants on the desk or keep a small tank of goldfish, so you can keep the air humidity around the environment, in the eye fatigue, you can also look at the green plants or fish tank swimming in the small fish, relax the eyes. In recent years, “dry eye”, which used to be seen as a disease of the elderly, has become common among young people. But ophthalmologists also point out that sometimes, it may just be a lack of water in the eyes, and does not affect the vision, and can be relieved by taking a break. This time you need to consciously find free time in the work, it is best to go for a walk during the lunch break, or every hour of work, take 10 minutes to close the eyes; eat more fresh fruits and vegetables to increase the intake of vitamins; drink more green tea to improve the hematopoietic function of the muscle, while preventing radiation damage. Also, remind the office white-collar workers, you can put the adjustment computer, 30 degrees look down at the computer can prevent eye dryness.
