Naphazoline is a vasoconstrictor. It works by narrowing swollen blood vessels in the eyes
to reduce eye redness.
Zinc is a mineral that is used in this medication as an astringent to gently clear proteins
and mucus from the outer surface of the eye.
The combination of naphazoline and zinc ophthalmic is used for temporary relief of
minor eye irritation such as redness, dryness, or burning. This medication is also used to clear
mucus build-up on the outer surface of the eye caused by dust, pollen, or smoke.
Naphazoline and zinc ophthalmic may also be used for other purposes not listed in this
medication guide.
