what causes eye pain and light sensitivity
Many causes of eye pain also cause the eye to look red (see Eye Redness). Other symptoms may be present depending on the cause of eye pain. For example, people may have blurred vision (see Vision, Blurred), a bulging eye (see Eyes, Bulging), or pain worsened by bright light. The cornea (the clear layer in front of the iris and pupil) is highly sensitive to pain.
