Children necessitate constant protection from sunlight, unlike the majority, who can remain under the sun for about an hour without burning. Limiting exposure to the direct Sun during midday hours can help prevent harmful UV radiation effects. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes. Foresee this! The reflection from snow can nearly double the intensity of UV radiation from the Sun.
