Meet the one-in-a-million 'moon boy' who wears a plastic visor wherever he goes because he is allergic to the SUN.
Oliver Kei, seven, was diagnosed with rare genetic condition xeroderma pigmentosum (XP) when he was 18-months-old after he developed dark freckles as a baby.
The disorder, which is estimated to affect one in a million people in the US, means his skin cannot repair damage caused by exposure to the sun’s rays and other UV light.
