Abstract: good eating habits are not only the guarantee of healthy body, but also the guarantee of healthy vision. The process of vision requires the participation of vitamin A, and the conduction of optic nerve needs the help of vitamin B. preventing presbyopia requires healthy blood vessels. Vitamin C and vitamin E contribute a lot to this.
eyes are the window of the mind. However, with the increase of learning pressure and work pressure, our eyes have an unbearable weight, and protecting our eyesight seems to become an eternal “proposition”. The health of eyes and the protection of eyesight need our joint efforts.
are the top 10 killers who damage eyesight. Accidental injuries
are natural and man-made disasters. Unexpected impact or injury to the head or eyes may affect eyesight. Such as firecrackers, car accidents, fist blows in the eyes, etc. The probability is small, but the damage is large.
is the ninth psychological factor
, which is a factor that is easy to be ignored. Excessive tension and depression have a certain impact on vision. Afraid to wear glasses, whether to wear them or not; Eager to wear glasses, should not wear disorderly, these seemingly psychological “tangles” will affect vision.
No. 8 eating habits
good eating habits are the guarantee of healthy body and healthy vision. The process of vision requires the participation of vitamin A, and the conduction of optic nerve needs the help of vitamin B. preventing presbyopia requires healthy blood vessels. Vitamin C and vitamin E contribute a lot to this. For example, in the absence of vitamin A, the eyes often feel dry and astringent, and are prone to fatigue. In serious cases, the white surface of the eyes is dry and wrinkled, and even lead to corneal ulcer.
have a fever of seventh eye diseases, such as
eye disease (red eye disease, keratitis, cataract, glaucoma, etc.), and the non eye diseases (diabetes, cervical cones, hypertension, persistent fever) may affect vision for a short time or a long time. Some drugs and viruses also affect vision.
Including eye drops, the use of which is dependent will also affect vision. Aging of the eye itself (macular lesions, decreased cone density, etc.) will also affect vision.
the sixth genetic
most of preschool children’s myopia comes from heredity. About 5% of the total myopia is caused by heredity. Both parents are highly myopic (more than 800 degrees), and children have a very high probability of myopia. Therefore, experts suggest that both parties with high myopia had better not get married.
No. 5 eye hygiene
bad eye hygiene habits have far-reaching destructive effects on eyes. Including excessive fatigue, dirty hands wiping eyes, reading in bed, etc. Do not underestimate! A bad habit is enough to destroy a pair of good eyes.
No. 4 environmental sanitation
there are many “adverse” environments that we can’t change. Around us, our eyesight is unknowingly damaged. Including the uneven reflection of the classroom blackboard, the wall is too bright, the lighting is too bright or too dark, and the desk and chair are inappropriate, which will directly and for a long time affect our eyesight, but we are unaware of it.
No. 3 watch TV
everyone with certain visual ability may watch TV. Watching TV is the occasion where we use our eyes most from a medium distance. TV itself has a certain flickering luminous body. In addition, the distance is relatively short and watching TV for a long time is prone to fatigue. Especially for children, their eyesight is not mature and easy to cause injury.
now mobile phones and iPads have not only “invaded” adults, but even become “nannies” with children. As the main force with the most eyes in this distance, those who secretly murder your eyesight can’t escape them.
rank second. The “killer” of reading and writing
covers a wide range, because we need to learn from childhood. In memory, our myopia deepens with the progress of learning. Reading and writing are completed through close-up fine vision, mainly relying on visual pyramidal cells. The excessive fatigue of visual cells will bring the fatigue of the whole visual system, and the corresponding pathophysiological changes will occur in the eye muscles and eyeballs.
come first. Using computers
almost all of our study, work, life and entertainment are inseparable from computers. This is a close-up illuminant. As the most frequent tool for us to use our eyes at close range, computer is also the source of the greatest fatigue to our eyes.
comes with dizziness, neck acid, etc. So it seems that slowing down eye fatigue with computers should also be put in the first place in our vision defense war!
