Common children's vision problems! Common children's vision problems include strabismus, amblyopia, ametropia and visual deprivation.

1. strabismus The so-called strabismus means that when a child looks at something, his eyes are inconsistent and he cannot rotate in the same direction. Common strabismus is that the eye position is inward or outward (esotropia or exotropia).

2. Amblyopia refers to poor eyesight in one eye or both eyes. Even after correction (wearing glasses with the right degree), the best vision can't reach the vision that can be achieved at that age.

3. ametropia The so-called "ametropia" means that the naked eye vision can't reach the normal standard (usually 0.8), and it is not caused by other diseases and needs to be corrected through optical lenses (wearing glasses). Common ametropia problems include myopia, hyperopia and astigmatism.

4. Visual deprivation, such as congenital cataract, congenital ptosis or corneal opacity, will lead to poor visual function.

In addition, children's congenital vision problems include congenital glaucoma, congenital cataract, congenital ptosis, amblyopia or color blindness. As for the problem of myopia that parents are most worried about, although the possibility of congenital myopia has been reported, according to epidemiological studies, the heritability of myopia patients is extremely low. In other words, most myopia patients are caused by the acquired external environment.

Vision care of Preschool Children: As mentioned above, one to three years old is the golden stage of vision development. In order to maintain children's eyesight health, parents should not only pay attention to the arrangement of family environment, provide a balanced diet, maintain regular work and rest, but also avoid any behavior that may damage children's eyesight.

Modern parents want their children to succeed, and many children start learning activities from kindergarten. When children's vision is not fully developed, excessive use of eyes may cause vision damage. It is suggested that it is best to use holidays to engage in outdoor activities with children and go to nature. In addition to helping children relax eye muscles, it can also enhance parent-child relationship.

3. Adequate and comfortable indoor lighting

Lack of light can easily make eyes tired. The most comfortable and clear luminosity is 20 watts, more than two fluorescent lamps or 60 watt electric lamps. When reading, the brightness of the desktop should be at least 350 candlelight, and the light should be irradiated from the left to avoid direct irritation to the eyes.

4. Reduce the negative effects of TV and computer.

Children are advised not to watch TV for more than 1 hour every day, and rest for 5 ~ 10 minutes every half hour. When watching TV, let the children be 6 ~ 8 times away from the diagonal of the TV screen.

Balanced nutrition.

The topic of "repairing eyes" has aroused extensive discussion. In addition to well-known vitamins A, B and C, Omega-3 polyunsaturated fats (such as DHA and EPA) which have recently caused a whirlwind in the medical field are nutrients closely related to retinal development and eyeball blood circulation. It is suggested that parents can help their children get balanced nutrition from different foods or nutritional supplements, so that their children can eat healthily and have good eyesight.

1.DHA and EPA

Studies have shown that DHA is an important component of phospholipids in retinal cells of eyes, accounting for about 50 ~ 60%. The higher the concentration of DHA, the better the vision. On the contrary, DHA deficiency may lead to poor eyesight of young children.

On the other hand, EPA is rich in a variety of protective factors beneficial to blood circulation, which helps to maintain high blood fluidity and inhibit abnormal blood agglutination. These special unsaturated fatty acids are mostly found in the fish oil of deep-sea fish, and the proportion that the human body can synthesize by itself is extremely low. For mothers who need breastfeeding and children whose functions are not yet mature, it is best to eat more deep-sea fish and supplement DHA and EPA necessary for retinal development. For mothers and children who don't like fish, it is recommended to choose some suitable nutritional supplements instead.

2. vitamin a

Vitamin A is an essential component of mucosal cell differentiation. If there is not enough mucus, the eyes will be dry, tired and congested. Adequate vitamin A can prevent eye dryness and discomfort, night blindness and dry eye. Food sources of vitamin A include animal liver, egg yolk, milk and dairy products, yellow-green vegetables and fruits.

3. Vitamin B group

Vitamin B group is a great contributor to maintaining the health of the optic nerve system, and the comprehensive intake effect is better than that of individual intake. Animal liver, milk, lean meat, green leafy vegetables, beans, wheat germ, brown rice and germ rice are all rich in vitamin B group.

4. vitamin c

Its main function is to resist oxidation, prevent the retina from being damaged by ultraviolet rays, increase the toughness of tiny blood vessels in the eye, repair cells, and help improve eye health. Basically, people can't store vitamin C, so they should take it from food every day. Dark green and yellow red fruits and vegetables are the best choice.

The above four foods are very important for the maintenance of eye health, and most of them can be obtained from daily diet. Therefore, parents should pay more attention to their children's daily diet and don't let their children eat too much finely processed food. If necessary, they can also follow the advice of ophthalmologists, choose some suitable nutritional supplements, and cooperate with normal work and rest and eye habits to make their babies have healthy and bright eyes. If they are jealous for a long time, they should pay special attention.
