Children's eyes are still developing, and one thing they can't do well yet is filter ultraviolet (UV) light. That makes kids more vulnerable to the sun than adults, especially toddlers and school-age children who spend hours playing outside. Doctors now recommend sunglasses for children the same way they recommend sunscreen.
Why are children's eyes more vulnerable to UV?
- A clearer lens: the crystalline lens inside a young eye is very clear, so more UV reaches the retina than in an adult eye.
- More time outdoors: children spend more of their day outside, often near sand, water or snow that reflect extra UV.
- Delicate skin: the thin skin around the eyes burns easily and is hard to cover with sunscreen.
- Damage adds up: UV exposure is cumulative. Exposure in childhood contributes to cataracts, pterygium and macular degeneration later in life.
In the short term, strong UV can also cause photokeratitis, a painful sunburn of the cornea with redness, tearing and light sensitivity.
What are the best sunglasses for kids?
- UV400 or 100% UVA/UVB protection. This is non-negotiable. Toy and novelty sunglasses often have no UV label at all.
- Not just dark. Dark lenses without UV filtering make the pupils widen and let more UV in. Tint and UV protection are separate.
- Polarized lenses cut glare from water, sand and pavement, so kids squint less and are happier to keep them on.
- Flexible, impact-resistant frames and lenses that survive drops, bends and playground knocks.
- The right size. Frames that slide down or pinch come off within minutes. Buy for the current size, not one to grow into.
What if my child won't wear sunglasses?
- Find a pair that is comfortable: light, soft on the nose and ears, and not touching the eyelashes.
- Let your child choose the colour. Ownership beats persuasion.
- Wear yours at the same time. Children copy what they see.
- Make it routine: sunglasses go on with shoes and sunscreen.
- For busy toddlers, a strap helps keep them in place.
If your child still resists, limit time in direct sun when UV is strongest, roughly 10am to 4pm, and use a wide-brimmed hat and shade.
Make eye protection normal
Some parents worry that sunglasses make a child stand out. In reality, the long-term benefits for eye health far outweigh that. The earlier sunglasses become part of going outside, the less of a battle they are.
