Red eye is a very common condition, where the surface of the eye appears red. Your eyes get red when the tiny blood vessels on the surface of the eyes expand and turn the whites of one or both eyes a pink or reddish tint. Many things can cause it, like a night of heavy drinking, or a physical injury to your eye. But if you haven’t had too much alcohol, or scratched or poked your eyeball recently, there are other possibilities.
Causes of Red Eye
Environmental Pollution: One of the most common causes of red eyes is allergens and irritants present in the environment such as pollen, dust, wind, dry air etc.
Lack of Sleep: People who do not get enough sleep will also experience red eyes.
Eye infections: Eye infections and inflammations can cause red eyes, as well as other symptoms such as itching, discharge, pain, and blurred vision.
Lack of clean contact lens: Improper care or use of contact lenses can cause redness in eyes.
Symptom of some disease: Red eyes can be like a symptom which indicates a more serious problem such as blepharitis, conjunctivitis, corneal ulcers, scleritis, or acute glaucoma. If you are experiencing other symptoms, such as discharge or pain associated with the redness, you should schedule an appointment with your eye-care professional or primary care doctor right away to see if one of these conditions is present.
Treatment for Red eye
It is good to take some precautionary measures if you are experiencing red eyes and irritation, so that the condition doesn’t get worse.
Avoid touching or rubbing your eyes.
If the environmental factors are bothering you, change your location or minimize your time there, if at all possible.
You could also try putting an ice pack on your eyes to relieve symptoms like swelling and pain, and may alleviate the redness.
You might also consider rinsing your eyes with cool water. This can work to irrigate and cleanse your eyes without harming them.
Getting plenty of sleep and eating a healthy diet keeps your eyes and other important organs healthy and resistant to infection.
