Red Eyes

What causes red eyes?

Red eyes happen when the small blood vessels on the surface of the eye expand, making the white part of the eye look pink or red. This can happen for many reasons. Common causes include tiredness, dryness, allergies, or irritation from contact lenses. Redness can also come from an infection, such as conjunctivitis (also called pink eye), or from environmental factors like smoke or pollen. Sometimes, red eyes are linked to more serious issues, such as uveitis or glaucoma, so if the redness doesn’t go away or comes with pain, it’s best to speak to a healthcare professional.

When should I see a pharmacist or doctor for red eyes?

You should speak to a pharmacist if your red eyes don’t improve after a few days, or if you’re unsure what’s causing it. They can help rule out common irritants and suggest the best treatment, like lubricating drops or antihistamines. You should see a doctor if the redness is sudden and severe, or if you also have pain, light sensitivity, blurred vision or discharge. These symptoms could mean an infection or something more serious. It’s always safer to get a proper check if red eyes are affecting your daily life or if they keep coming back.

Can I use eye drops every day for red eyes?

Yes, you can use most lubricating or hydrating eye drops every day to relieve redness and dryness. These are sometimes called artificial tears. They help to keep your eyes moist and comfortable. If your eyes feel dry often, using these drops regularly can prevent redness before it starts. However, avoid using decongestant eye drops every day, as these can cause rebound redness if used too much. Always read the label or ask a pharmacist before starting new drops, especially if you wear contact lenses or have other eye conditions.
