Signs You May Need to See a Doctor
Discharge from the Eyes
White, yellow, or green discharge in addition to redness may be a sign of bacterial conjunctivitis, which affects the white of the eye. Bacterial conjunctivitis can be sight-threatening without appropriate treatment.
Blurry Vision or Sensitivity to Light
If red eyes are accompanied by sensitivity to bright light or blurry vision, or both, you may have a condition known as uveitis. Uveitis can present with or without pain and should be treated promptly by your doctor to prevent lasting problems.
Pain or a Foreign Body Sensation
Materials like metal shavings, sawdust, and sand can become embedded in the cornea and cause a serious infection. If you experience redness as well as pain that gets worse when you open or close your eye, you may have a foreign body in your eye. This corneal condition requires urgent attention from a doctor.
