How to Use Eye Drops Correctly

Published: October 19, 2026Updated: October 19, 2026

Administering eye drops properly ensures your medication reaches the ocular tissues effectively while minimizing systemic side effects. Whether you are treating glaucoma, infections, allergies, or dry eyes, mastering the correct instillation technique prevents contamination and medicine wastage. Always follow specific dosing instructions provided by your ophthalmologist, optometrist, or pharmacist.

Quick Summary

Wash your hands, tilt your head back, pull down your lower eyelid to create a pocket, instill a single drop without touching the tip to your eye, and gently close your eye while pressing the inner corner for one to two minutes.

Step-by-Step Guide

1

Wash your hands and inspect the bottle

Thoroughly wash your hands with soap and water for at least 20 seconds, then dry them with a clean, lint-free towel. Inspect the medication bottle to confirm it is the correct prescription, check the expiration date, and shake gently if the solution is a suspension. If you wear contact lenses, remove them unless your eye care provider explicitly instructed otherwise.

Important: Never touch the dropper tip with your fingers or allow it to touch your eye, eyelid, or any other surface, as this can introduce harmful bacteria into the bottle.

2

Position your head and form a pocket

Tilt your head back comfortably and look upward toward the ceiling. Using the index finger of your non-dominant hand, gently pull down your lower eyelid to create a small pocket or pouch (the conjunctival fornix) between your eyeball and the lower lid.

3

Instill a single drop into the lower lid

Hold the dropper bottle upside down directly over your eye using your dominant hand, resting your hand against your forehead or cheek to steady your aim if needed. Squeeze the bottle gently until exactly one drop falls into the lower eyelid pocket. Avoid placing the drop directly onto the sensitive cornea in the center of the eye.

Important: The eye can hold only one drop at a time; instilling extra drops will simply overflow onto your cheek and waste medication.

4

Close the eye and apply punctal occlusion

Gently close your eye and keep it closed for one to two minutes without blinking repeatedly, squeezing, or rubbing. Place your index finger over the inner corner of your eye (next to the bridge of your nose) and apply light pressure. This technique, called punctal occlusion, prevents the drop from draining through the tear duct into your nasal cavity and bloodstream.

Important: Blinking rapidly or squeezing your eyelids shut tightly can pump the medication out of the eye before it has time to absorb.

5

Blot excess liquid and replace the cap

Use a clean tissue to blot away any excess liquid that overflows onto your cheek or eyelid margin. Immediately replace and tighten the cap onto the dropper bottle without wiping or rinsing the dropper tip.

6

Space multiple medications appropriately

If you are prescribed more than one type of eye drop, wait at least 5 to 10 minutes before administering the next medication. If you use both liquid drops and an eye ointment, always instill the drops first and wait 10 minutes before applying the ointment to ensure both absorb properly.

Important: Applying two different drops back-to-back will cause the second drop to wash away the first, significantly reducing its therapeutic effectiveness.

Frequently Asked Questions

Why is it important to press the inner corner of my eye after applying drops?
Pressing the tear duct (punctal occlusion) blocks the drainage pathway that connects your eye to your nose and throat. This keeps the medicine on the surface of the eye longer for maximum therapeutic benefit and prevents it from entering the bloodstream, which reduces systemic side effects like changes in heart rate, blood pressure, or unusual taste.
Can I use eye drops while wearing contact lenses?
Generally, you should remove contact lenses before applying medicated eye drops unless specifically told otherwise by your doctor. Preservatives common in eye drops, such as benzalkonium chloride, can accumulate in soft lenses and cause corneal irritation or damage. Wait at least 15 minutes after instilling the drops before reinserting your lenses.
What should I do if I am unsure whether the drop actually went in?
Because the eye holds only a tiny volume of liquid, if you feel the coolness of the drop or if any liquid spills onto your cheek, part of the drop almost certainly entered the eye and you should not add another. If you are certain you completely missed the eye, you may instill one single replacement drop.
How long can I keep an eye drop bottle once it is opened?
Most prescription and preserved over-the-counter eye drops must be discarded within 28 to 30 days of opening to avoid bacterial contamination, even if medicine remains in the bottle. Preservative-free single-dose vials must be discarded immediately after a single use. Always verify storage and disposal guidelines on your medication packaging.
