Question: What is the ruling regarding wearing coloured contact lenses with the justification [for doing so] being for beautification and following the latest trend (fashion), keeping in mind that their price is no less than 700 [Saudi] Riyals (approximately £120)?
Response: There is no harm in wearing contact lenses due to necessity; As for other than that, then it is better to leave doing so especially if they are expensive, since this equates to being excessive in [spending one’s wealth] which is prohibited, in addition to that which exists therein of deceit and covering up the reality because they make the eyes appear in other than their natural state without there being a [Islaamically justifiable] need for that.
