Have you ever watched the rising sun or gazed it transcending into the darkness? I guess most of you do this every day in your life. But Riley McCoy isn’t allowed, not at least without any protection sheets!

Riley McCoy aged 17 waits all day to enjoy her time out of the window glasses because of a rare inherited disorder which is known as Xeroderma Pigmentosum. In this peculiar disease, any exposure to UV rays causes a blistering burn, potential malignant cancer, internal organ damage and eventually death.
