If your eyes feel dry, itchy, or red, you’ve probably reached for an eye drop. They’re simple liquids that sit on the surface of your eye to lubricate, treat infection, or reduce inflammation. Most people think eye drops are only for allergies, but there are dozens of formulas for different problems.
Lubricating drops – also called artificial tears – are the go‑to for dry‑eye symptoms. They add moisture and can be used anytime, even if you wear contacts. Look for preservative‑free bottles if you need many drops a day.
Allergy drops – contain antihistamines or mast‑cell stabilizers. They calm itching and redness caused by pollen, pet dander, or dust. Most work within minutes and last a few hours.
Antibiotic drops – prescribed for bacterial infections like conjunctivitis. They kill bacteria and should be used exactly as your doctor says, usually several times a day for a week.
Anti‑inflamatory drops – include steroids or non‑steroidal agents. They reduce swelling after eye surgery or injury. Because steroids can raise eye pressure, only use them under medical supervision.
Glaucoma drops – lower the pressure inside the eye to prevent optic nerve damage. There are many brand‑specific formulas, and consistency is key for them to work.
First, figure out why you need drops. If it’s just dryness, a preservative‑free artificial tear is usually enough. For redness that won’t go away, see a pharmacist or doctor before you pick a decongestant, because overuse can cause rebound redness.
When you buy online, check that the seller is a licensed pharmacy and that the product has a valid Canadian health number. Cheap generic drops can be safe, but only if they come from a reputable source.
Before each use, wash your hands and avoid touching the tip of the bottle with your eye or fingers – that keeps germs out. Tilt your head back, pull the lower eyelid down gently, and squeeze one drop in the pocket. Close the eye for about 30 seconds without blinking hard; this lets the medicine spread.
If you use more than one type of drop, wait at least five minutes between them. This prevents the first drop from being flushed out by the second.
Store drops according to the label – most need to stay at room temperature and away from direct sunlight. Some lubricating drops last only a month after opening; mark the date on the bottle to avoid using expired fluid.
Finally, watch for side effects. A mild stinging sensation is normal for many drops, but persistent pain, blurred vision, or a sudden increase in eye pressure means you should stop using the product and call a professional.
With the right type and proper technique, eye drops can quickly bring comfort back to your eyes. Keep these tips in mind, choose a trusted product, and you’ll see the difference in no time.
