What is the requirement for eyeglasses sold to children under 18 years old?

The requirement that eyeglasses sold to children under 18 years old should use shatter-resistant materials is important for safety reasons. Children are more prone to accidents and rough play, which can lead to injuries if their eyewear is not made from durable materials. Shatter-resistant lenses significantly reduce the risk of injury from broken glass or plastic fragments, promoting eye safety for younger individuals.

While polycarbonate lenses are indeed a common recommendation due to their lightweight and unbreakable nature, the overarching requirement focuses on shatter resistance as a general safety standard. Lenses made of materials that resist shattering ensure that in the event of an impact, the lenses will not break into sharp pieces that can harm the child.

Having a prescription for eyeglasses is a separate requirement that ensures proper vision correction but does not specifically address the material safety standards that are crucial for children's eyewear. Therefore, while all options touch upon important aspects, emphasizing shatter-resistant materials is aligned with the priority of safeguarding children's health and well-being when it comes to eyewear.
