As log as it was in your eyes and not in your nose or mouth, the fast
is valid.

my eyes were sore and i used honey solely for lubrication purposes. it taste did not reach my throat, but due to ‘Gastroesophageal reflux disease’ i keep having this ‘post nasal drip’ sometimes while fasting, which involuntarily reaches the stomach. today with the drip i found a taste of honey. my question is, is my fast still valid.
