Be careful, children can really develop myopia through “eating”!

For children, the temptation of sweets is irresistible. Sweet candies, delicious cakes, cool ice cream, soda drinks of various flavors... Children can't pull their legs away when they see them. But parents should pay attention that children who eat too much sweets will not only gain weight, get cavities, but also myopia. Therefore, parents must control their children's sweets intake.

Eating more sweets can accelerate myopia

The eyeballs of children and adolescents are in the development stage, the eyeball wall is very stretchable, and the sclera is hard and elastic. When calcium is deficient, the strength of the sclera will be relatively reduced, and under the long-term mechanical pressure of the extraocular muscles, the eyeball wall tends to gradually stretch, from a spherical shape to an elliptical shape, and the distance from the cornea and lens to the retina is thus lengthened, so that the image cannot be formed on the retina, thus causing myopia.

Sweets are a favorite food for many children, but sugar needs a lot of vitamin B1 when it is metabolized in the body. If too much sugar is consumed, vitamin B1 will be insufficient. Vitamin B1 deficiency will affect the growth and development of the optic nerve, leading to vision loss. ** Excessive intake of sugar will also reduce calcium in the body, weaken the elasticity of the eyeball, and promote the occurrence and development of myopia.

Carrots and pork liver are good to eat in moderation

In our country, there has always been a tradition of dietary therapy, and various eye-protecting foods are also popular, such as carrots and pork liver. Indeed, eating carrots is good for the eyes , because carrots are rich in beta-carotene, which can be converted into vitamin A-retinol in the human body. Retinol is the key to synthesizing the photosensitive substance rhodopsin in visual cells. Adequate intake is helpful in preventing myopia and night blindness.

In addition to carrots, pumpkin, sweet potato and dark green leafy vegetables (water spinach, spinach, broccoli, etc.) are all good sources of beta-carotene.

The liver is an important organ for storing vitamin A in animals. 100 grams of pork liver contains about 5,000 micrograms of vitamin A, which plays a certain role in maintaining healthy vision, but it cannot prevent the occurrence of myopia. Eating more may not be good for the body, so just consume it in moderation.

The key to protecting eyes lies in eye protection habits. In addition to diet, parents should also pay attention to supervising their children to develop good eye habits.

Keep your eyes at a certain distance from electronic screens and books. When looking at a tablet, the distance should be no less than 40 cm. If watching TV, the distance should be at least 6-8 times the diagonal of the TV screen. If reading a book, keep your eyes one foot away from the book.

Participate in more outdoor activities . Studies have shown that sunlight can stimulate children's vision development, so children can participate in more outdoor activities. It should be noted that the time period and duration of outdoor activities should avoid the hot midday period.
