I read a fatwah from Shaykh Muqbil, may Allah have mercy on him, about the wearing of contacts and he said it was permissible. However I know for certain that the solution put into the eye enters the back of the throat and thus into the stomach.
So my question is, does contact solution that you put into your eyes when one puts contacts in break your fast, as in as it a form of nutrition? May Allah reward you with goodness.
Shaikh Hassan Al-Banna:
It’s allowed to use the solution but if it reaches the throat, then do not swallow it, you must spit it.
