A, the characteristics of mosquito flying disorder
(A) physiological mosquito flying disorder
A little bit of two points of black shadow, flying around in front of the eyes, sometimes you can see, sometimes not. When people are very tired and tired, will feel the mosquitoes move especially obvious, and older people have flying mosquitoes phenomenon, will feel more intense and obvious than the middle-aged flying mosquitoes phenomenon.
This kind of flying mosquitoes is benign, called physiological flying mosquitoes. Experts believe that about 80% of the flying mosquitoes by the formation of vitreous fiber hydration, is physiological flying mosquitoes.
(B) pathological mosquitoes
Pathological mosquito flying disorder has 3 characteristics.
①. There is an abnormal flash.
②. The number of flying mosquitoes keeps increasing in a short period of time.
③. The vision has the feeling of being blocked.
Pathological flying mosquitoes usually caused by serious diseases, is due to the vitreous body near the retina, optic nerve, ciliary body and other structures of the pathology caused by changes in the vitreous body.
Suddenly there are a lot of flying mosquitoes, a lot of flash, see things distorted, straight line becomes distorted, face becomes distorted and other strange phenomena, mosquitoes flying direction and uncertain, black shadow obscuring the field of vision, poor vision, visual field defects, etc., are must pay attention to the evil signs, indicating that the vitreous body may be in acute degeneration, or the retina has the risk of hole, to quickly see the ophthalmology examination retina. If the diagnosis is indeed, often need surgery.
Second, the treatment of mosquito flying disorder
Got mosquito flying disorder to treat, in addition to treatment, but also pay attention to maintenance. Specific practices are as follows.
1, usually pay attention to rest do not overuse of eyes, to avoid the formation of myopia. Do not “eyes do not turn”, pay attention to the frequency and complete blinking action, often blinking can reduce eye exposure to the air time, to avoid tear evaporation.
2, do not blow too long air conditioning, avoid airflow over the seat, and place tea near the seat to increase the surrounding humidity.
3, eat a variety of fruits, especially citrus fruits, should also eat more green vegetables, grains, fish and eggs. Drinking more water is also helpful to reduce dry eyes.
4.Maintain good living habits, get enough sleep and do not stay up late.
5.Avoid long time continuous operation of computer, pay attention to rest in between, usually 1 hour continuous operation, rest 5-10 minutes. When resting, you can look away or do eye exercises.
6, maintain a good working posture. Maintain a most appropriate posture, so that the eyes flat or mildly downward looking at the fluorescent screen, which can make the neck muscles relaxed, and make the eye exposed to the air to reduce the area to a minimum.
7, adjust the distance position of the fluorescent screen. The recommended distance is 50-70 cm, and the fluorescent screen should be slightly lower than the horizontal position of the eye 10-20 cm, a 15-20 degree downward perspective. Because the angle and distance can reduce the need for refraction and reduce the chances of eye fatigue.
8, if you would have less tear secretion, eyes prone to dryness, in front of the computer is not suitable for the use of contact lenses, to wear frame glasses. People who wear contact lenses in front of the computer, it is also best to use varieties with a high degree of oxygen permeability.
9, people over 40 years old, it is best to use bifocal lenses, or when typing.
