Final answer:
The best time to give eye drops/ointment is in a dark or dimly lit environment after allowing your eyes to adjust for about 15 minutes.
Step-by-step explanation:
When applying eye drops or ointment, it is best to do so in a dark or dimly lit environment, as this allows the pupils of your eyes to open up and receive the medication more effectively. It is recommended to give your eyes about 15 minutes to get 'dark adapted' before applying the drops or ointment. This is similar to how your eyes adjust to the darkness of a movie theater.
