Sunglasses manufacturers say that not only adults need sunglasses, but especially children in June also need sunglasses. Many "fashionable parents" often wear sunglasses when taking their children out. More important than being cool and handsome is that children have delicate eyes that are more resistant to strong sunlight and require shielding and protection. However, many online articles say that wearing sunglasses seems to be detrimental to children's visual development. Yes or no? What exactly should I choose?
The damage of ultraviolet rays to the eyes can be divided into acute and chronic damages. When the eyes are exposed to sunlight for a long time, UV damage to the eyes can slowly accumulate, causing chronic damage. Children's corneas and lenses are more transparent than adults, and are more susceptible to harmful light intrusion and damage. If you do not pay attention to protection, it may damage the child's cornea and lens, and lead to burns in the macular region of the retina, laying a hidden danger for future eye diseases such as cataract. Children's annual UV exposure is three times that of adults, with 80% of their lifetime UV exposure occurring before the age of 20. Therefore, it seems necessary to take UV protection measures for children's eyes.
Ophthalmologists say that people aged 0-3 are not recommended to wear sunglasses. 0-3 years of age is a "critical period" for children's visual development. Infants before the age of 3 need more bright light and clear object stimuli to develop their visual function. After wearing sunglasses, the light within the visual range will darken and the pupils will correspondingly enlarge. Children's eyes lack time to integrate into normal light environments, and the macular area of the fundus cannot be effectively stimulated. Visual function may be affected as a result, and in severe cases may lead to amblyopia. In addition, infants before the age of 3 have very few opportunities to go out, and the time is also very short. Even when they go out, there are protective measures such as a stroller awning, so they don't need to wear sunglasses. Parents should pay attention to protecting their baby's eyes and can choose to wear a sunshade for their child.
After the baby reaches the age of 3, his visual development has reached a relatively complete level, and his time out has also increased. He may be exposed to more ultraviolet rays outdoors. When children are exposed to strong light, such as in snowy mountains, oceans, grasslands, beaches, etc., it is necessary to wear sunglasses to provide radiation protection for their eyes. However, children do not approach adults until around the age of 6, as their eyes and vision develop. Children under the age of 6 should wear as few sunglasses as possible. It is best to keep the wear time within 30 minutes and not exceed 2 hours each time. Sunglasses should be removed immediately after entering the room or in the shade.
Children after the age of 6 should not continuously wear sunglasses for more than 4 hours. Even adults are discouraged from wearing sunglasses for long periods of time, as sunglasses can expose people's eyes to relatively dim light, causing their pupils to inadvertently dilate. If their eyes stay in this state for a long time, their eyesight will decrease. Wearing sunglasses for a long time can also cause the angle of the anterior chamber to narrow, which may lead to poor drainage of aqueous humor. Over time, it is easy to induce acute episodes of angle closure glaucoma.
In fact, before the age of 12, it is a sensitive period for children's visual development. You should be careful when wearing sunglasses. It is only recommended to wear sunglasses outdoors in strong sunlight, preferably for no more than 4 hours. Whether to wear sunglasses depends mainly on the intensity of the sun's rays, not the season, as the intensity of the sun's rays varies greatly between seasons and regions. It is necessary to wear sunglasses when the sunlight is relatively strong, or when the surrounding environment strongly reflects sunlight, such as when standing on reflective large areas of water.
It should be noted that it is best for children not to wear adult sunglasses. First of all, this model is too large for the child to walk after wearing it. Secondly, if glasses are too heavy, they can cause pressure on the child's nose. How can I choose the right pair of sunglasses for my child?
