Kids, Glasses and Safety
Once you and your child agree on frames that you both like, the next consideration is the lenses.
Children under the age of 18 should have lenses made of polycarbonate or a material called Trivex, because these lightweight materials are significantly more impact-resistant than other lens materials.
Polycarbonate and Trivex have built-in protection against potentially damaging ultraviolet (UV) rays, and the lenses are scratch-resistant coated by the manufacturer or fabrication lab.
Because of safety and liability issues involed and the concept of “duty to warn,” Wink eyewear does not sell children’s eyewear with anything less shatter resistant than Poly or Trivex. As a general rule, we also prefer to use Trivex when available because the optical qualities of Trivex are far superior to Poly and the materials are priced the same.
