Which route corresponds to administration to the eyes?

Explanation:
Ophthalmic administration is the route used for delivering meds to the eye. It covers eye drops, ointments, and gels applied directly to the ocular surface for local effect. This distinguishes it from other routes: otic is for the ear, oral goes through the mouth into the GI tract, and rectal is through the rectum. While ophthalmic formulations mainly target the eye locally, some drug can reach the systemic circulation via tear drainage into the nasal mucosa and bloodstream, so PK considerations include tear dynamics, corneal permeability, and nasolacrimal drainage.
