In general, this way to mimic those popular icons is ok. Parents do not need to dissuade their children from choosing their favorable models. Actually it is important for parents to encourage their children to make their own decisions based on personal preferences. In addition, a child will take good care of his or her glasses only when he or she likes it. Allowing children to choose their favorable glasses further helps them to protect their eye when doing outdoor exercises.
While most kids have specific tastes about sunglasses colors and brands, durability elements such as spring hinges and flexible materials are helpful for mischievous children. Spring hinges allow the temples to bend in wider angles and flexible frame materials such as polycarbonate offer the best protection to children. Polycarbonate lenses are lighter and more impact-resistant. In addition, thinner, lighter and stronger materials such as stainless steel and titanium are also gaining popularity. Besides new designs, manufacturers also offer extended warranties on children's sunglasses.
The most common practice taken by eyewear manufacturers to guarantee the durability of children's sunglasses is to utilize tough, thin and lightweight polycarbonate lenses. These lenses have almost been the standard for kid's sunglasses in this industry. Polycarbonate lenses will hardly crack or shatter even if they are hit during rough-and-tumble play or sports. Due to this optical feature, polycarbonate lenses mean not only durability for children, but also a maximum degree of eye protection. Most children spend much time in doing active outdoor games or sports.
Conventional designer sunglasses are now available for children with a size adjustment. Older kids opt to choose branded or licensed eyeglasses, while Puppies, Stride Rite and Disney are popular among children at all ages. Due to children's fragile eyes, UV protection is one of the most important factors of children's sunglasses. Both traditional sunglasses and lenses aim at blocking out as much as harmful UV rays from sunlight. Clip-on sunglasses are another convenient option.
