Red eyes can show up after a long day at the computer, a poor night of sleep, or time outdoors during allergy season. Sometimes they clear quickly on their own. Other times, redness is your eye’s way of telling you something needs attention.
Dr. Jonathan Davis and his team help patients identify the cause of red, irritated eyes and determine the right next step. While many cases are related to dryness or allergies, persistent redness, pain, or vision changes should never be ignored.
Common causes of red eyes
Redness happens when the small blood vessels on the white part of the eye become enlarged or irritated. Common triggers include:
- Dryness from reduced tear production, screen time, wind, or air conditioning
- Seasonal allergies, which may also cause itching and watery eyes
- Contact lens irritation or overwearing lenses
- Lack of sleep, smoke exposure, or eye makeup irritation
- Eye infections, including conjunctivitis, commonly called pink eye
- A scratched cornea, foreign object, or other eye injury
Dry eye and allergies can look similar
Dry eye and allergies can both leave your eyes looking red and uncomfortable. Dry eye often causes burning, grittiness, fluctuating vision, or the feeling that something is in your eye. Allergies are more likely to cause itching, watering, and swelling around the eyes.
Here in the Tennessee Valley, seasonal pollen can make allergy-related irritation especially frustrating. A dry eye evaluation in Decatur, AL, can help determine whether your symptoms are related to your tear film, allergies, or a combination of both. Knowing the differences between dry eye and allergies can also make recurring symptoms easier to recognize.
Contact lenses may be part of the problem
Contact lenses can contribute to red eyes when they become dry, collect deposits, or are worn longer than recommended. Redness that improves after removing your lenses but returns when you wear them again is worth mentioning at your visit. A contact lens exam can help determine whether a different lens material, replacement schedule, or care routine may improve comfort.
When red eyes may be an emergency
Not every red eye needs urgent care, but certain symptoms should prompt you to call an eye doctor right away. Seek emergency eye care if redness comes with:
- Sudden or worsening vision changes
- Moderate to severe eye pain
- Light sensitivity
- A chemical splash, foreign object, or eye injury
- Significant swelling or discharge
- Redness after sleeping in contact lenses
- A severe headache, nausea, or halos around lights
These symptoms can be associated with infections, corneal injuries, acute glaucoma, or other concerns that need prompt treatment. Avoid using leftover prescription drops or someone else’s medication, since the wrong treatment can sometimes make the problem worse.
Pink eye is not the only explanation
Pink eye is a common cause of red, irritated eyes, but it is not the only one. Viral, bacterial, and allergic conjunctivitis can each cause different symptoms and may require different care. If redness is paired with discharge, crusting, or exposure to someone with an eye infection, understanding pink eye symptoms, causes, and treatment options can help you recognize when to schedule a visit.
