Answered by Shaykh Faraz Rabbani
Is it allowed to keep contact lenses in whilst performing Wudu ?
Walaikum assalam,
Contact lenses are worn inside the eye. It is neither obligatory nor recommended to wash inside the eyes in wudu or even in ghusl. [Tahtawi, Hashiyat al-Maraqi]
As such, wearing contact lenses in no way affects the validity of one’s wudu.
Walaikum assalam,
Faraz Rabbani
