Ultraviolet (UV) radiation comes from direct sunlight and reflected sunlight. The direct exposure is more intense at higher altitudes and between 9 and 3 during the summer. Reflected light accounts for 50% of UV radiation and is most intense from snow, water and sand.
Children’s eyes are particularly susceptible to damage from sun:

  • Children spend more time outdoors. In fact they receive 80% of their lifetime UV exposure before the age of 20 years.
  • More UV radiation is transmitted through the young crystalline lens to the retina. The tissues are clear and don’t block as much light.
  • Babiators

Most children don’t experience photophobia or sensitivity to light. Wearing sunglasses needs to be a habit just like riding in a car seat or wearing a bike helmet. Children don’t want to wear a helmet, but it is required, just as sunglasses should be required.  The use of good UV blocking sunglasses prevents cumulative damage  to the eyes.
