Red eyes are a common symptom of allergies and can be caused by a variety of factors, such as pollen, specific foods, or even chemicals. Fortunately, there are several over-the-counter medications available that will reduce the burning sensation and irritation caused by red eyes. If these remedies do not work, you may want to consult your primary care physician. Alternatively, you may find that your eye condition is caused by dry eyes, which can lead to inflammation and reduced tear production.
In addition to red eyes, many people also experience blurred vision or halos around lights. In cases of these symptoms, you should consult an eye doctor, as redness may be a sign of more serious eye problems. The doctor will perform a basic eye exam to determine the cause of redness, and will also check your vision, eye movement, and eyelid health. Then, he or she may recommend a course of treatment or refer you to an eye specialist for further testing.
Other common causes of red eyes include smoke, smog, dust, and household cleaning and personal care products. Additionally, red eyes can be a symptom of a more serious medical condition, such as acute glaucoma or eye injury. If red eyes persist for more than two hours, see a doctor immediately.
Once you stop exposure to the allergen, the redness will subside. The process may take some time, but it can be accelerated if you apply a cool compress to the eyes. You can also use over-the-counter eye drops that are designed to combat allergic reactions. However, it is still best to figure out what caused the reaction and try to avoid the allergen in the future.
Another common cause of red eyes is seasonal allergies. The best way to prevent seasonal allergies from affecting your eyes is to limit your exposure to pollen, dust, and pet dander. However, if you are sensitive to these allergens, you can also consult a doctor who can prescribe you antihistamines.
Some of the reasons why your eyes are red are minor, but can be life-threatening. While red eye is not a cause for alarm, you should always consult a healthcare provider to rule out any more serious problems. It is best to consult a physician if your red eye becomes persistent or if it is affecting your vision.
If your red eyes are causing pain, you should consult a doctor immediately. A break in the blood vessels can cause red eyes. These blood vessels can be broken by a strong sneeze, hard vomiting, or rubbing your eyes too hard. You may also be suffering from an infection, which in turn could cause red eyes.
Other reasons why your eyes are red can be triggered by an allergy. When you have an allergy, your body releases a substance called histamine that causes your eyelids to swell. The resulting inflammation causes watery, red, and itchy eyes. Blepharitis is another cause of red eyes. This condition causes inflammation and causes eyelids to swell and produce excessive tears.
