Recently see a lot of online vision problems, especially children myopia problem more and more serious, more and more young age.Little age book did not read how many, myopic glasses than who wear early.
There is corrective surgery, but there seems to be an age limit, 18 years old.Before that goes to school during, no matter be study life or movement, myopia can bring very big inconvenience to the child, had better let the child be not myopia namely.What should parents do?
1. Normal value of children's visual acuity
Parents should clearly understand that "the normal value of children's vision"
The lower limit of normal vision for children ages 3 to 5 is 0.5;The lower limit of normal visual acuity for children over 6 years of age is 0.7;A child's vision doesn't reach 1.0 until after age 7.Parents should be clear about the normal value of children's vision, can not take 1.0 vision requirements of children under 7 years old, so as not to blindly think that children amblyopia, or amblyopia children's vision correction is excessive.
2. Early symptoms of myopia in children
1. You like to squint: Long-term squinting causes eye muscle fatigue, and myopia deepens faster.
2. See things too close: see things from very close, watch TV involuntarily go forward, often prompt children's vision becomes worse.
3. Rub the eyes often: myopic children see things blurred, eye fatigue, often rubbing the eyes may prompt the child's vision decline.
4. Frequent blinking: myopic children will often rub their eyes, resulting in chronic conjunctivitis and corneal injury, eye discomfort, and children will frequently blink.
5. Often tilt the head or cross-eyed to see things: exclude strabismus, myopic children like to tilt the head or cross-eyed to see things, because it can reduce the scattering of light, so as to see something clear.
6. Frown often: Frowning can cause changes in the eyelids and extraocular muscles, changing the shape of the eyes, so that you can see more clearly.
7. Often pull the corner of the eye: this can reduce the scattering of light, and flatten the cornea, change the refractive power, so that mild myopia vision temporarily improved.But long - term pull canthus, can cause astigmatism.
