Daily outdoor activities for 2 hours, can effectively prevent myopia date: 2016-06-06 14:04
June 21 is the 21st national eye-loving day. The theme of this year's love-eye day event is to protect the eyes and start small. In recent years, the problem of adolescents with refractive errors in China has become increasingly prominent, and the rate of poor vision has remained high. According to a recent national student health survey, pupils aged 7 to 12 years old, 13 to 15 years old junior high school students, and 16 to 18 years old high school students and The rate of bad eyesight among 19 to 22-year-old college students was 45.71%, 74.36%, 83.28% and 86.36%, respectively. Wang Jing, deputy chief physician of Department of Ophthalmology at the First Hospital of Nanjing City, said that vision is the most compulsive sensory function in humans. Starting from the moment of crashing, we must begin to protect our eyes and have a pair of good eyes that are not born in one step. Is gradually developed and improved, if you can stay outdoors for 2 hours a day or 10 hours a week, you can play a better prevention of myopia.
Visual development is divided into three stages:
The first stage: 0-6 months
Newborn: With visual ability, but not very clear.
1 month: You can see about 20cm in front of the object.
3 months: Forming a gaze ability, the eyeball can move freely.
6 months: Forming binocular vision with the ability to determine distance and depth.
From birth to 6 months is the most important period of visual development. From the beginning, the baby can only distinguish between black and white and can gradually distinguish colors such as red, yellow and blue. At this stage, parents can give the baby some black and white contrasting or colorful pictures to promote the development of the baby's visual area. Second stage: 6 months - 3 years old
1 year old: Has formed a relatively perfect visual function, depending on the 0.2 or so.
3 years old: Children can basically learn to check the visual acuity chart. Parents can regularly check their eyesight with children.
This stage allows the baby to play with some geometric toys, talk about the shape and color of the toy, and enhance visual functions such as stereo vision. Stage 3: 3 years old and above
3 years old: The average visual acuity is 0.5.
4-5 years old: The average visual acuity is 0.6.
6-7 years old: The average visual acuity is 0.7.
7 years old or older: The average visual acuity is 0.8 or more.
At this point, care should be taken to prevent the child from having amblyopia and refractive errors.
Amblyopia and refractive errors: When the corrected visual acuity is lower than the above-mentioned average age of children of the same age; or when the difference between the best corrected visual acuity of the two eyes is large, the poorer eye is amblyopia. Here we say that corrected vision refers to the vision that can be achieved after optometry. Therefore, when parents find that the child's vision is lower than the average level of children of the same age, it should be dilated optometry to see if the degree of normal conditions, without particularly anxious immediate treatment of amblyopia. Nearsightedness, farsightedness, and astigmatism, all of which are considered to be refractive errors, simply mean that the degree of the eye exceeds the normal range even if the refractive error is not correct. Contrast amblyopia, refractive error is not just to wear glasses, vision can be corrected to normal, but not amblyopia. At the time of birth, due to the small eyeballs, they are usually in farsightedness. As the eyeball grows up, it gradually develops in the direction of facing. At this time, due to heredity, environment, use of eye habits, etc., some children may experience myopia prematurely; if only normal myopia, take corrective measures. Just because of myopia too early, without control, it is easy to become high myopia. High myopia is a terrible thing. It can make the eyeballs grow longer and the retina becomes thinner. It can not only lead to blindness in itself, but also has the risk of developing retinal detachment and glaucoma more than ten times bigger than normal people.
Wang Jing suggested that starting from childhood, in order to avoid becoming a high myopia in the future, parents should pay special attention to protecting the child's eyes and preventing myopia! It is currently recognized that the most effective way is to increase children’s outdoor time and stay outdoors for 2 hours each day. Or 10 hours a week, you can play a better prevention of myopia. (
