During winter, snow sports such as skiing and snowboarding increase exposure to
UV rays, as snow reflects up to 80 percent of sunlight. This can cause
actinic keratitis, an inflammation of the cornea similar to a burn.
According to Dr. Francesco Nizzola, ophthalmologist at Poliambulatorio Chirurgico
Modenese, the condition manifests as pain, burning, redness and a feeling of
sand in the eyes. The sea, water and sand also amplify the effect of UV rays,
increasing the risk.
It’s not just natural environments: unprotected showers and sunbeds can promote
keratitis, while there is no evidence that blue light from digital screens has similar effects.
Prevention is key: proper sunglasses and caps with visors in
children help reduce risk, even on cloudy or shady days.
