Children's sunglasses selection should be rigorous
In summer, the sun is dazzling, and many parents also want to buy sunglasses for their children. But how to buy sunglasses is the key. Now Xiaobian and you introduce the precautions when buying children's sunglasses.
First, the harm of buying the wrong children's sunglasses
The choice of children's sunglasses really needs to be taken seriously. Because children's eyes are not yet mature, they cannot wear glasses casually like adults. In fact, children's eye development also needs the stimulation of external sunlight and objects, which is good for children's eye health.
Once a child wears sunglasses with poor filtering effect, it is easy to block the light and reduce the clarity of what the child sees. Children's eye development requires retinal high-definition imaging. If sunglasses are worn at this stage, the child's vision development will be affected. The probability of causing myopia will be higher. However, some high-standard glasses pay more attention to the influence of this aspect, and pay more attention to the filter processing when designing sunglasses.
Second, the purchase of children's sunglasses precautions
1. Children's sunglasses lens selection. When buying children's sunglasses, the choice of lenses is very important. We try to choose resin type or PC lenses, which are less likely to break. Children are more lively and active, if you choose fragile lenses, it is easy to cause children to be injured.
2. Children's sunglasses should pay attention to UV protection. We generally wear sunglasses outdoors in direct sunlight, mainly due to the strong outdoor ultraviolet radiation, which will damage our eyes. Therefore, the ability of sunglasses to isolate ultraviolet radiation is stronger. When we buy children's sunglasses, we need to pay attention to the correlation coefficient of UV protection. If it can be 100% UV resistant, it is still very good.
