First of all, the anti-blue lens is a functional lens, because it can prevent harmful blue light from entering people's eyes, thus preventing macular degeneration. But now many places are recommending this topic to everyone who wears glasses. In fact, this lens is more suitable for people with high demand, such as computer workers. This kind of lens is not suitable for children in general. After I went to get my glasses, people didn't advise me to equip my children with anti-blue lenses, because they said that blue light can be divided into harmful blue light and beneficial blue light. Because children are developing and need beneficial blue light to enter, they feel that they are really conscience shops.
