Dought & clear - Ruling on eye drops for one who is fasting

If the bitter taste of eye drops enters the throat, does it break the
fast? If you put the eye drops induring the day and thengo to sleep,
and do not know whether you swallowed it, what is the ruling?.
Praise be to Allaah.
The scholars differed concerning eye drops and whether or not
theybreak the fast.
The view favoured by Shaykh al-Islam Ibn Taymiyah and by ShaykhIbn
'Uthaymeen, is that they do not break the fast.
Shaykh Ibn 'Uthaymeen said:
Shaykh al-Islam Ibn Taymiyah was of the view that kohl does not break
the fast, not even if the taste of the kohl reaches the throat. He
said, this is not called food or drink, and it is not like food or
drink, and it does not have the same effect as food or drink. There is
no saheeh hadeeth from the Prophet(peace and blessings of Allaah be
upon him) which expressly indicates that kohl breaks the fast, andthe
basic principle is thatit does not break the fast. An act of worship
remains valid unless it is proven that it is invalidated. What he said
is correct, even if a person can taste it in his throat. Based on the
view favoured by Shaykh al-Islam, if a person puts drops in his eyes
whilst fasting and tastes it in his throat, that does not break his
fast.
