A person's vision is not fixed until after the age of 22. So children should pay attention when they are young:

1. Children are not allowed to watch TV before the age of 3, and do not want children to watch TV to coax him when they make trouble, which will cause the child's vision to form amblyopia (which can be changed through **) or astigmatism.

2. Adults should also sacrifice the hobby of watching TV (which can be appropriate after the child falls asleep), but play more with the child, so that the child can have a happy childhood.

3. Give your child more fish, eggs, milk, fresh vegetables and fruits in the diet.

4. Take your child to the hospital for eye examination regularly so that it can be prevented as soon as possible.

5. Don't take your child to the eye store to get glasses easily. Instead, you have to go to the hospital to get checked and determine what type of myopia it is, and then go for glasses. Otherwise, the prescription of the glasses will become deeper and deeper.

There will also be an increase in vision care franchises.

Therefore, vision care is particularly important.

The profit is particularly high, and the vision care industry is also a market for entrepreneurs to compete for, but if you want to do a good job, you have to work hard, and the publicity of this piece is very important, and the popularization of vision care knowledge needs a long way to go, take your time!
