It contains small blood vessels that becomes reddish or pink when the eye is inflamed and therefore making the white part of your eye to change the color.

What Causes Pink Eye

Pink eye results from the following:

  • Allergic reactions
  • Viral infections
  • Bacterial infections
  • Chemical splashes into the eyes
  • Eye contacts with foreign objects

Allergic conjunctivitis

Allergic conjunctivitis results from various allergens such as smoke, pollen grains, cosmetics, perfumes and dust mites. Balsam of Peru found in different drinks for flavor, medicine for healing and in toiletries for fragrance can also cause this condition.

When you are exposed to the above allergens, your body responds by producing an antibody known as immunoglobulin. The immunoglobulin will therefore trigger the mast cell found in the conjunctiva to release an inflammatory substance such as histamine. Your body will therefore respond to histamine by showing the various symptoms of pink eye like redness, irritations and tearing. In most cases, the allergic conjunctivitis normally affects both eyes.

Viral conjunctivitis

Viral conjunctivitis usually affects one eye. The infection can also spread to the other eye if not controlled. It is usually accompanied with other symptoms of a common cold such as red eyes, running nose and sore throats and other problems of respiratory system.

The viral infection usually results to production of clear watery mucous discharge from the eyes for 7 to 14 days of infection. The viral type is highly contagious and can easily spread to un- infected individuals through direct contact with the discharge, sharing of handkerchiefs and towels. Avoid spreading this infection by washing your hands and handkerchiefs using warm salt water.

Bacterial conjunctivitis

Like a viral infection, this type can also affect one or both the eyes. The bacterial conjunctivitis normally produces thicker discharge from the eye that is yellow or green in color as compared to a viral infection. It is common among children than adults.

It is also contagious and can easily be spread though body contact with the discharge and other secretions from the eyes. The bacteria that is responsible for this infection is known as staphylococci and streptococci. Other bacteria such as chlamydia trachomatis can cause this condition but the symptoms of pink eye may not be that much severe.

Chemicals and foreign objects

Irritations from chemical splash and eye contact with foreign objects may also cause conjunctivitis. Cleaning of the eye with water to get rid of such chemicals and objects may cause irritations, dilation of blood vessels and tearing of the eye. This condition normally clears up faster within 2 days unlike to infections that may take longer time to clear up according to Mayoclinic.

There are also other risk factors that may cause the outbreak of this condition.  The risk factors depend on the type of conjunctivitis. They include the following:

  • Exposure to the viral or bacterial that causes conjunctivitis.
