This life, each stage has things to do and distances that can be calculated.
These three things are irreversible once they happen
It's not "not knowing what to pay attention to," but "knowing what to pay attention to, but eye care is at the bottom of the list because of doing homework until 10 o'clock every day."
Verification Signals (more than two are considered valid):
· Outdoor activities for less than 1 hour a day
· Continuous close-up work for more than 40 minutes without rest
· Vision decline or dental problems have occurred
The child is not nearsighted, has good teeth, and sits up straight
Don't have to keep an eye on his posture every day
Find a sport that can be persisted in (jumping rope/swimming/sports)
Definition
Daily outdoor time · Vision (naked eye) · Number of dental caries · Posture assessment
How to measure
Check vision every semester; record outdoor time every day; see a dentist once a year
Healthy Range
Outdoor ≥2 hours/day · Naked eye vision ≥1.0 · No new dental caries · Posture can be maintained for 30 minutes
Only relying on eye exercises —— Limited effect, outdoor activities are the core
Buying an eye-care lamp is enough —— The lamp is not the main cause, the distance and time of eye use are
Only pay attention to nearsightedness when it happens —— Nearsightedness is irreversible, only the progression can be controlled
Don't worry about baby teeth decay —— It will affect the development of permanent teeth and chewing
Wear a back brace for a long time —— The muscles will become weaker, and exercise is needed
Ensure 2 hours of outdoor time every day (even if it's in segments, the key is natural light)
20-20-20: Look at something 20 feet away for 20 seconds every 20 minutes
Reading and writing distance: eyes 1 foot from the book, chest 1 fist from the table, hand 1 inch from the pen
Brush your teeth 2 times a day + see a dentist once a year
Choose a sport that can be persisted in (jumping rope/swimming/sports)
This is the direction and judgment, not a diagnosis. Decisions involving medication, examination, and surgery must be made by a doctor.
Seek medical attention immediately if the following conditions occur: persistent chest pain, shortness of breath, sudden severe headache, change in consciousness, severe bleeding, high fever lasting more than 3 days.
