Final answer:
Eye drops should be applied to the conjunctival sac, and afterward, pressure should be applied to the nasolacrimal duct at the inner canthus to optimize absorption.
Step-by-step explanation:
When applying an eye drop, you should aim to dispense the liquid into the conjunctival sac, which is the space between your eyeball and the lower eyelid. After the eye drop has been applied, you should apply pressure to the nasolacrimal duct, also known as the tear duct, to prevent the liquid from draining away too quickly. This is located at the inner canthus, the corner of the eye nearest the nose, where the eyelids come together.
