Abstract: perhaps many parents did not understand this situation of their children. Although most of their children’s vision will gradually develop normally with age, if they do not pay attention to protecting their eyes in the critical period of development, it may affect their vision for a lifetime.
children can only see things within 15cm at the beginning of their birth, and their eyesight is about 0.1; At the age of 1, the visual acuity was about 0.3; At the age of 3, the visual acuity was about 0.6; At the age of 5, the visual acuity was about 0.8; At the age of 7, the visual acuity was about 1.0. Children are not born with a pair of “bright” eyes, but their eyesight will develop better and better as they grow up. Most children are “hyperopia” before the age of 7.
maybe many parents did not understand this situation of their children. Although most children’s eyesight will gradually develop normally with age, if they do not pay attention to protecting their eyes in the critical period of development, their eyesight may be affected for a lifetime. Parents should not only let their children watch electronic products, but also be careful of the damage to their children’s eyes caused by toys! Before the age of 7 is the key period for the development of children’s retina. The following toys should be purchased carefully!
1 luminous toys
when children’s vision is not fully developed, they are often particularly interested in bright and luminous objects because they are easier to identify visually. But those toys that can emit strong light or color light should not be bought for children. When a child’s eyes are irradiated by strong light or flickering light, the ciliary muscle will always be in a state of excessive contraction, which will not only weaken vision, but also damage the retina. Especially in the dark environment, luminous toys do more harm to children’s eyes. Such as waving fluorescent sticks, colorful headwear, etc. In addition, children often play with this colorful luminous toy, which is also easy to affect their ability to distinguish natural colors.
warm tips: the infrared light emitted by the laser pen and laser gun is very harmful to children’s eyes, and it must not be bought for children as toys. If the infrared ray directly irradiates the child’s eyes, it is easy to lead to the child’s vision decline, eye deformation, and even the risk of blindness.
2 “aggressive” toys
boys often like guns, cars, guns, robots and other toys. If the toys are equipped with music or similar functions, they will love them even more. However, these toys are often accompanied by “aggressive”, especially gun toys, which pose a greater potential threat to children’s eyes. For example, children’s simulated toy pistols are common in the market. If children hold a gun with “bullets” and “shoot” at children at close range, they are likely to hurt children’s eyes.
another example is the pressurized water gun that we often play with children in parks or scenic spots. The experiment shows that the pressurized water gun can easily shoot through the fresh-keeping film when it is 10 cm away from it. Imagine how dangerous it would be if the pressurized water gun accidentally shot into the child’s eyes!
warm tips: if children must play with “aggressive” toys, parents should take protective measures in advance, and it is best to wear protective glasses for children.
3 Toy glasses
for many businesses, they usually produce children’s sunglasses and color glasses as toys. The workmanship and light transmittance of their lenses are very poor, so they can’t be worn as glasses. If children often wear such glasses, they are likely to cause a series of symptoms, such as red eyes, photophobia, blurred vision, decreased color discrimination and so on.
warm tips: maybe many parents will ask: can children wear sunglasses? The American Academy of Pediatrics (AAP) suggests that children over 6 months old can wear sunglasses. However, children are in a critical period of eye development after all. It is best not to wear sunglasses for more than 2 hours, and must choose products from regular manufacturers.
4 inferior toys
Inferior toys are mostly three no products, with cheap materials, uneven color distribution, and even a pungent smell. Some will also add various additives, which release harmful substances such as formaldehyde, benzene and phenol, which are very harmful to children’s health. For example, for inferior dyed or painted toys, if children rub their eyes with their hands after playing with such toys, they may cause eye infection, conjunctivitis and other eye diseases. For another example, the edges and corners of inferior toys are usually not smooth enough. Children are naturally lively and active. In the process of playing, toys with edges and corners are likely to pose a threat to children’s eyes. Under
, the quality of the little yellow duck for bathing is uneven in the market. Most of the products produced by informal manufacturers are made of dyed plastic. This material smells pungent and is easy to carry germs. Children often play with such toys, which is very harmful to their body and eyes.
in addition to these, what my mother would like to remind parents is: don’t choose too fine toys for too young children. For example, too small beads and jigsaw puzzles. Because when the function of children’s eyes is not well developed, looking at too small things may make children form the habit of squinting and then affect the development of their eyesight.
in short, when buying toys for children, we must choose toys produced by regular manufacturers. Take preventive measures, parents can rest assured, and children have a good time.
