The lens material that is most commonly recommended for children and athletes due to its safety features is polycarbonate. This material offers significant advantages because it is highly impact-resistant, meaning it can withstand the rigors of sports activities and the playful behavior of children without shattering. Polycarbonate lenses are less likely to cause injury in the event of an impact, which is crucial for the safety of active individuals.

While Trivex is another option that provides good impact resistance and optical clarity, polycarbonate is often the preferred choice in these scenarios because it is lighter and thinner, making it more comfortable for children and athletes who need to wear glasses frequently during physical activities. Additionally, polycarbonate also provides built-in UV protection, which is essential for outdoor sports.

Other materials like high-index lenses and glass are not typically recommended for children and athletes. High-index lenses can be thin and light but do not offer the same level of impact resistance as polycarbonate. Glass, while providing excellent optical clarity, is fragile and can shatter, posing a higher risk of injury.
