There are many different conditions and injuries that can cause there to be pain in a person's eye including blepharitis, conjunctivitis, corneal abrasions, corneal infections, glaucoma, foreign particles in the eye, iritis, sinusitis, stye, optic neuritis, blocked tear ducts, pink eye, dry eye, chalazion and allergies, according to the Mayo Clinic and WebMD. To determine the exact cause of the pain in one's eye, a trip to the doctor's office is often necessary.
Not all of these eye pain problems require a medical professional treatment as they will go away on their own, however, in some cases the condition cannot relieve itself until it is medically treated reports the United States National Institute of Health. At home, a person can try to rest their eyes if eye strain is part of the problem. A person can also try to wash their eyes with water if there are foreign particles such as dust or allergens in the eyes. Finally, a person who wears contacts can try wearing glasses instead to avoid further irritating the eyes.
If the pain is severe or if there is any redness, swelling, pressure or discharge around or in the eyes then it is necessary to see a doctor reports the U.S. National Institute of Health. At the doctor's office, there will be an examination that checks the pressure of the eye as well as a sit-lamp examination and a fluorescein examination. Many medical professionals will also check the eyes with a light to see how the pupils respond.
