Editing Moonlight (section)

==Folklore==
In folklore, moonlight sometimes has a harmful influence. For example, sleeping in the light of a full Moon on certain nights was said to transform a person into a [[werewolf]]. The light of the Moon was thought to worsen the symptoms of [[lunatics]], and to sleep in moonlight could make one blind, or mad.<ref>''A Dictionary of English Folklore'', Oxford University Press, 2000</ref> [[Nyctalopia]] (night blindness caused by a lack of vitamin A) was thought to be caused by sleeping in moonlight in the tropics.

"[[Moon blindness]]" is a name for equine recurrent uveitis. Moonlight is no longer thought of as the cause.
