Eye pressure pain, or any eye pain that is felt below the surface of the eye, can be a sign of a serious medical condition. According to Mayo Clinic, individuals should seek immediate medical attention if the pain is severe or includes loss of vision.
Some common causes of eye pain include allergies and inflammation of the eyelids. Pressure under the eye can cause glaucoma by damaging the nerves in the eye. Glaucoma gradually diminishes a person's ability to see. The Mayo Clinic advises a person to seek medical attention if they show symptoms of glaucoma.
