Causes of red eye

    What causes bloodshot eyes?

    Those who suffer from repeated occurrences of red eye will know that having the condition can feel irritating. While there are many ways to treat red eye, in this article we specifically look at the causes and symptoms, and try to understand ultimately what it all means for people who suffer from it, so they can be more prepared if they happen to experience it frequently.

    What is Red Eye?

    Red eye, also known as bloodshot eyes, is a condition that can be associated with soreness and may involve other symptoms. When the eyes are red it is because more blood than usual is flowing through the small blood vessels of the eye.

    The Causes of Red Eyes

    There are many causes for different forms of red eye, although mainly these are separate from those that are outlined below.

    The cause of eyes turning red are most likely due to minor problems, such as burst blood vessels, conjunctivitis or particles entering the eye. In these cases, the condition does not tend to affect your vision and should improve by itself. Red eye could also stem from chlorine in swimming pools, lack of sleep, eye strain, or smoky or polluted air.

    If your red eye doesn’t start to improve after a few days, you should see your doctor. If you suffer from recurring eye ailments, or experience pain, then you may also need to consider seeing a doctor to help find out what could be the cause.

    The Symptoms of Red Eye

    Eye watering or gritty eyes are also typical symptoms and feelings associated with red eye. If you experience any of the symptoms listed below, go to see a GP as soon as you can, as these may indicate a more serious condition:

    • Severe ocular pain
    • Reduced visual acuity
    • Light sensitivity

    Some Ways to Prevent Red Eye

    Many cases of redness can be prevented by trying to avoid associated causes. Here are some tips:

    • If your eye becomes contaminated, you may find it necessary to flush it out immediately, but try to use an approved eye wash solution
    • Avoid activities that can cause eye strain, such as reading for too long in poor light or looking at the TV or computer screen for excessive periods of time.
    • Do not wear contact lenses longer than recommended by your optician.
    • Clean your contact lenses as instructed and regularly.
    • Remove all makeup from your eyes each day.
    • Wear sunglasses out of doors in the sun. This can help protect against airborne irritants as well as dryness.

    Stop using and consult your pharmacist or doctor if you have eye pain, changes in vision, increased redness or no improvement after 24 hours. FOR EXTERNAL USE ONLY. Do not use eye drops whilst or just before wearing soft contact lenses, or if you suffer from eye disease or have had eye surgery. Prolonged use may increase redness of the eye.
