Sore and swollen eyes may be related to visual fatigue, glaucoma, dry eye and other causes. 1. Visual fatigue: due to prolonged inappropriate use of eyes, such as excessive use of computers and other electronic products, can cause dry eyes, triggering visual fatigue, resulting in soreness and swelling of the eyeballs. 2. Glaucoma: Glaucoma caused by elevated intraocular pressure can result in soreness and pain in the eyeballs, accompanied by vision loss and visual field defects. 3. Dry eye: Insufficient tear secretion or excessive evaporation can lead to soreness and swelling of the eyeballs, photophobia, vision loss and other symptoms. If the soreness and swelling of the eyeballs can not be relieved by rest, it is recommended to go to the hospital in time to clarify the cause of the disease and carry out standardized treatment under the guidance of the doctor, so as to avoid the delay of the disease to bring adverse effects on the body.
