In their Keeping Kids Healthy column, UTMB Drs. Sally Robinson and Keith Bly warn that children are particularly vulnerable to the harmful ultraviolet A and B (UVA and UVB) damage that can accompany sun exposure. The American Optometric Association has found that the lenses of young eyes are more transparent than that of adults, risking retinal exposure to a greater degree of short wavelength light. “It is important that parents make sure the sunglasses fit their child’s face properly and shield the eye from the sun’s rays in all directions. The lenses that wrap around can provide additional protection for the retina and the skin around the eye. Lenses made of polycarbonate or Trivex materials are the most impact resistant.”
