The eye is the window of the soul, it allows us to see the beauty of the world but also helps us to distinguish between right and wrong, black and white, and have a pair of bright eyes, for each of us is very important. If you don't want to wear childrens glasses at an early age, follow these ways to protect your eyes.

There are two main reasons for myopia:

1. Hereditary. That is, both parents are highly myopic (above 600 degrees), and the genetic risk is as high as 50%.

2. Environment. It is mainly caused by excessive use of eyes.

In life, many parents will ignore the signs that some children are starting to be nearsighted, thus delaying the best time for treatment.

So, which small details should be paid attention to by parents?

If the child begins to lose sight of the blackboard, squints or always frowns and rubs his eyes, and indicates that he can see more clearly after rubbing his eyes, then he or she should consider whether the child is inclined to be nearsighted or is already nearsighted.

At this time, we should take the child to the hospital for examination as soon as possible to determine whether it is really myopic.

If children are guaranteed two hours of outdoor exercise every day, in addition to special genetic factors, such children are generally not prone to myopia.

If you can't guarantee the amount of exercise because of your studies, parents can take their children out to play more during the holidays.

Outdoor sunlight is conducive to the synthesis of dopamine, and dopamine has a certain effect on the prevention and control of myopia, which is very helpful in the protection of children's eyesight.

To read and write, you should sit and achieve the "three ones", that is, one punch from the table, one foot from the book, and one inch from the tip of the pen.

Don't bend over when reading, don't read lying down, don't read while walking or riding in the car.

The time for class, reading, and writing should not exceed 40 minutes, and the time for operating the computer should not exceed 30 minutes. If you have to do your homework for a long time, it is recommended to give your child a little rest for about 15 to 20 minutes, even if you close your eyes for a few seconds or turn your eyes.

The second is the rational use of electronic products. When parents accompany their children, they should minimize the use of electronic products and consciously control the use of electronic products by their children, especially preschoolers. The use of electronic products for non-learning purposes should not exceed 15 minutes at a time, and should not exceed 1 hour a day. After using electronic products for 30-40 minutes, you should take a rest and relax for 10 minutes. The younger you are, the shorter the time for continuous use of electronic products should be.

In 2019, 25.3% of children aged 2–17 years wore glasses or contact lenses, and the percentage increased with age among both boys and girls. Among boys, 3.0% wore glasses among those aged 2–5 years, 20.0% among those aged 6–11 years, and 35.3% among those aged 12–17 years. Among girls, the corresponding percentages are 3.1, 26.4, and 48.2. The percentage was higher among girls than boys overall and among those aged 6–11 years and 12–17 years, but not in the youngest age group.

Generally, there is no minimum age for children to start wearing glasses. There are some guidelines supported by the American Academy of Ophthalmology that can help decide whether to dispense glasses. For a child between one and two years old, glasses are generally recommended if the myopia (nearsightedness) is more than -4.00, the hyperopia (farsightedness) is more than +5.00 without strabismus or +2.00 with strabismus, or the astigmatism is greater than 2.50. If there is a difference in the refraction between the eyes, glasses may be recommended as well. It is important to remember that each child is unique and a pediatric ophthalmologist will help decide if these guidelines apply to your son.
