Tumefaction is another common symptom of the pink eye. Because the conjunctiva gets swollen, an inflammation takes place. It can be noticed inside of the eyelids as well as membrane surrounding the white area of this organ. The tumor of this type won’t be seen with the naked eye – a patient can only feel it. A regular activity like blinking becomes a challenge when such swelling occurs. Except for the feeling of having tired eyes and poor vision, the person believes there is a foreign body in the eye, causing such discomfort.
