Lens options for kids: what actually matters
When you order children’s glasses you’ll usually be asked about lens material and coatings. Here’s what tends to matter most for kids.
Impact resistance
Children’s lenses are commonly made from polycarbonate or Trivex. Both are lightweight and far more impact-resistant than standard plastic or glass, which matters for children who play, fall and occasionally get hit by balls.
Scratch-resistant coating
Kids put glasses down lens-first, wipe them on their t-shirts and drop them in sand. A scratch-resistant coating helps the lenses last.
UV protection
Polycarbonate and Trivex block ultraviolet light, which is useful because children spend a lot of time outdoors.
Anti-reflective coating
This reduces glare and reflections. It isn’t essential for every child, but it can help with screens and night-time lighting, and it makes the eyes easier to see in photos.
Light-reactive lenses
Lenses that darken in sunlight can be handy for kids who would otherwise need separate prescription sunglasses. Your optician can tell you whether they make sense for your child’s prescription and activities.
