    If we get our conjunctiva infected, the blood vessels within it may be irritated. This will give your eyes a red appearance. Dry eye syndrome may lead to redness in our eyes. When our tear glands can't produce sufficient quantity or quality of tears to lubricate and nourish our eyes, we may possibly suffer from red eye. You can apply artificial tears to lubricate your inflamed and irritated eyes. But if you got the chronic dry eye, you'd better ask an eye doctor for more professional treatment.

    The common causes of red eyes include allergy and contact using. Some people are allergic to foreign substances such as dust, pollen or certain chemicals found in makeup or contact lens solutions. Their immune system will reacts to these foreign substances. Their bodies will releases histamine to fight off the allergens. However, the histamine will cause blood vessels in our eyes to enlarge this will make our eyes to become red. Another main culprit of red eye is over wearing contact lenses. And this will cause eye infections such as keratitis or fungal eye infections. Under such circumstances, we must remove our contacts immediately and visit our eye doctor.
