It's back to school! In the past few days, the thrilling "Chinese speed", "winter vacation miracle" and "unfinished building rush site" must be deeply impressed, whether it is the winter vacation homework rush, or after the start of school for a long time with eyes to study, parents should pay more attention to their children's learning status and eye habits, when they find that their children have crooked vision, frequent squinting, squeezing eyes and other myopia-related symptoms, they should take their children to the hospital in time.
The new semester has begun, and in the face of the ensuing heavy schoolwork, children's eyes are under pressure. Please check this eye-loving advice from Director Song Aiping of Yiyang Aier Eye Hospital!
1. Pay attention to eye rest.
Reduce the behavior of using eyes at close range, read and write continuously for more than 40 minutes, and rest for 10 minutes every 40 minutes or so.
After 30 40 minutes of using electronic devices to study in your spare time, you should take a break and relax for 10 minutes. Use of electronic devices for non-learning purposes for no more than 15 minutes at a time.
2. Maintain a correct reading and writing posture.
One fist, one foot, one inch", that is, sit straight and upright at the table, with a fist from the table with your chest, one foot (33 cm) from the book, and one inch (3.) from the tip of the pen with your fingers holding the pen3 cm).
3. Pay attention to the eye environment.
Do not read, read, or use electronic devices while walking, eating, staying in bed, in a rocking carriage, or in low light or direct sunlight.
4. Take eye exercises seriously.
When doing exercises, pay attention, close your eyes, and carefully and correctly press and rub the acupuncture points, etc., to feel the soreness.
5. Increase the time for outdoor activities.
It is recommended to spend no less than 2 hours outdoors every day, and on weekends when there is plenty of time, you can take your children to do outdoor sports such as climbing, swimming, and playing ball.
6. Control the frequency and duration of use of electronic products.
Strictly limit the daily screen time, and the use of electronic products for non-learning purposes should not exceed 15 minutes at a time, and the cumulative time per day should not exceed 1 hour. Parents should do more parent-child reading, parent-child sports, parent-child games, etc., with their children, so that children do not indulge in electronic products.
7. Get enough sleep.
Ensure that children get enough sleep, 10 hours for elementary school students, 9 hours for junior high school students, and 8 hours for high school students.
8. Check your eyesight regularly.
Even if the child's eyesight is very good, it is recommended that parents take their child to a regular eye hospital for medical optometry every six months to track the child's vision development and achieve early detection and early intervention.
In addition, for children who have become myopia, it is necessary to take scientific methods to control the rapid growth of myopia and avoid the development of high myopia. For example:
1. Orthokeratology lenses.
It is a kind of glasses that can correct myopia and delay the growth of myopia. The corneal refractive rate can be changed by wearing it at night, and there is no need to wear glasses during the day.
Orthokeratology lenses are designed with a special inverse geometry, and their inner surface is made up of multiple arcs.
Changing the corneal geometry through physical pressure flattens the curvature of the cornea, thereby changing the power of the eye and forming myopic defocus in the peripheral retina, which is more effective in preventing the progression of myopia.
2. Multi-point defocus glasses.
It is a frame lens designed using the principle of defocusing myopia in the center and periphery. After wearing this lens, the object will form a focused image and a myopic defocus image in the eye, and the defocus image can control the axial growth of the eye and delay the progression of myopia, which is also one of the methods that have been clinically proven to control the progression of myopia.
3. Atropine.
Atropine is a kind of cycloplegic eye drops, which are commonly used in ophthalmology before dilated refraction for children under 12 years old.
In addition to the mydriatic effect of atropine, studies have shown: 05% low concentration of atropine eye drops has a certain effect on controlling the growth of myopia.
Song Aiping, director of Yiyang Aier Eye Hospital, reminded everyone that orthokeratology lenses and multi-point defocus glasses have medical attributes, and have high requirements for fitting accuracy and customized processing, and after wearing, regular follow-up visits by professional ophthalmologists are required to monitor changes in power and axial length, so you must go to a professional ophthalmology medical institution for examination and fitting.
The prevention and control of myopia requires the joint efforts of parents and children, starting from multiple aspects and taking comprehensive measures to effectively protect children's vision health.
