7 Causes of Red Eyes

If you suffer from bloodshot eyes, which is different from pink eye, there are a number of causes that could be the reason for it. Before you visit an eye doctor, like our Sammamish optometrist at NewVision Eyecare, here are some of the most common causes of red eyes, which some can easily be remedied with a few optometry treatments.

What Are The Causes of Red Eyes?

1. Allergens: Many airborne allergens can irritate your eyes and cause redness, including dust, pet dander, pollen, and mold spores. Allergy symptoms, in addition to red eyes, may include watery eyes or a burning sensation of the eyes.

2. Air Pollution: If you live near heavy road traffic or factories, the cause of your red eyes may solely be air pollution. Contaminated air may contain toxic fumes, dust and dirt particles, and even aerosolized chemicals that are released from manufacturing plants.

3. Chemical Exposure: Direct exposure to household cleaning chemicals can irritate and redden eyes. Always check the instructions on household chemicals and cleaning supplies to determine if the area needs to be ventilated before using. Common items such as bleach and ammonia can irritate eyes and other mucous tissue such as nose and throat.

4. Eye Infection: Red eyes can signal an eye infection, which may be caused by bacteria, fungi, or viruses that attack the eye. Rinsing the eye with saline solution can be helpful, but if eye redness continues and you suspect an eye infection, you should visit our Sammamish eye doctor for treatment.

5. Dry Eyes: Dry eyes can be a painful nuisance, and the condition is often connected with an inadequate amount of tears. But for many others, dry eyes can be due to the lack of blinking, which is needed to keep the eyes lubricated. Dry eyes are commonly relieved with an over-the-counter medication, but our eye doctor can prescribe the proper eye solution to treat severe dry eyes.

6. Contact Lens Wearers: For some people, wearing contact lenses can create a very uncomfortable condition of red, dry, and painful eyes. Often, the culprit is not the contact lenses, but the bacteria build-up that would normally be flushed out of your eyes if you were not wearing contacts.

7. Eye Injury or Trauma: Always speak directly to a medical professional or optometrist if you have experienced any trauma or physical injury to the eyes. Redness, swelling, and pain of the eye area should be immediately treated before an infection or loss of vision occurs.
