There are some trends in children's eyewear: Designers have taken cool and classic designs that work for adults and scaled them down for kids. Don't be surprised if your child wants eyeglasses that look a lot like yours.Branded or licensed eyewear lines grab a child's attention. Fisher-Price, Hush Puppies, Stride Rite, Disney and Marvel Comics appeal to kids of all ages, but especially to very young children. Lines related to extreme sports (X-Games), basketball (Nike, Converse) and other sports are very popular with slightly older kids.Spring hinges, strong and flexible frame materials and impact-resistant polycarbonate or Trivex lenses all help protect your child's eyes as well as your financial investment in his or her eyewear.
