Ash-Shaykh Saalih al-Fawzaan, may Allah preserve him, was asked on the
ruling of wearing coloured contact lenses?
A: It is okay to wearing contact lens due to a need for it . As if there
is no need for it then it is better to leave it off especially if it is
expensive for verily it is considered to be extravagance, adding to that
it contains of deceit and deception because it shows not the actuality
of the eye without there being a need for it.

59, print: as-Saffaa.
The scholars of the Standing Committee said:
It is not permissible to use artificial nails, false eyelashes and
coloured contact lenses, because it is harmful to the part of the body
where they are used and because it also involves deceit and trickery,
and is changing the creation of Allaah.
