Understanding Eye Redness Causes


Many factors can make your eyes turn red. They include infections, irritations, allergies, and sometimes diseases. Most of the cases, eye redness isn’t serious and will easily clear up without any treatment. Eye redness may be due to swollen or leaking blood vessels. When these blood vessels leak or swell, the white part of the eye becomes red. In some instances, eye redness may need a call to your eye doctor. It is important to see eye specialist such as LensCrafters for an extensive eye check-up and recommendations.

Minor Reasons for Eye Redness

Redness of eyes that doesn’t cause pain or disturb vision typically doesn’t require treatment.

  • Allergies. Dust and pollens may cause a type of conjunctivitis that isn’t infectious. So can sun exposure, dry eyes, and other small particles that get into the eyes. If this happens, use a cold pad or eye drops to soothe the eyes. Wear contact lenses only when the eye redness clears.
  • Viral conjunctivitis. This cause of abrupt eye redness commonly starts in just one eye. The virus makes blood vessels that covers the eyeball swell. Eyes may feel watery and itchy. There should be no pain or any alteration in vision. This type of irritation usually go away in just a couple of days. It is important to wash hands often and avert close contact.
  • Subconjunctival hemorrhage.  An abrupt high pressure from straining or coughing can cause blood vessel burst on the surface of the eye. Those who take blood thinners as maintenance are more probable to experience this. These bleeds don’t cause loss of vision or pain. They will almost usually clear up in just a week or two.

Serious Causes of Eye Redness

Redness of eyes with pain, loss of vision, inflammation or thick discharge may necessitate an immediate treatment.

  • Uveitis. This is the inflammation in the central layer of the eye. A common type is iritis, which affects the iris, or colored part of your eye. Symptoms include red eye, sensitivity to light, blurry vision, and pain. An eye surgery or injury or rheumatoid arthritis can cause this kind of eye redness.
  • Bacterial conjunctivitis. This condition is more severe than viral conjunctivitis. Infection caused by bacterial can result an ulcer to generate on the inside part of the eyelid. Thick discharge, itching, and pain are the common symptoms of this infection.
