Is it permissible to suffice with tears to purify the eye after impurity has reached it, or is it obligatory to wash it with water, knowing that excessive washing has led to weakened vision and eye sensitivity?

It is not a condition for purity to insert water into the eye; rather, it is a blameworthy form of exaggeration. One must be careful not to surrender to obsessive thoughts, for the religion is ease, and doubts do not remove certainty.
