This friend, your eyes are often swollen and painful, and your right eye has more frequent attacks and severe pain, which must arouse your great attention and vigilance! Generally speaking, eyeball swelling and pain may have the following reasons. First, visual fatigue, excessive or overworked eyes, but generally speaking, if the eyes get enough rest (sleep), most of the pain symptoms are relieved. Second, ametropia, binocular or monocular myopia astigmatism, hyperopia astigmatism or compound astigmatism, which will lead to binocular pain symptoms in severe cases. Third, glaucoma, high intraocular pressure in both eyes or eyes leads to swelling and pain in both eyes or eyes, often accompanied by headache, nausea and even vomiting on one side. Press the eyeball vertically with your fingers (index finger or index finger plus middle finger), and the eyeball is hard (normal eyeball is soft). 4. Inflammation, including conjunctival inflammation, scleritis or other inflammation in both eyes or one eye. 5. Other diseases. The symptoms of your complaining about eye pain are very serious. Personally, I suggest that you go to the local large general hospital ophthalmology or ophthalmology hospital as soon as possible to conduct a comprehensive examination and diagnosis of your eyes (especially to exclude glaucoma and eyeball inflammation) and treat them symptomatically, so as not to delay your illness, delay treatment and cause irreversible damage to your eyes. Besides, I want to warn my friend. First, getting sick is not terrible. The terrible thing is that if not treated in time, it will delay the illness and cause irreversible damage. Second, pay attention to eye hygiene at ordinary times, avoid excessive and overloaded use of eyes, learn to do eye exercises (online self-study), stay up late less, exercise more, improve the body's immunity, scientifically protect the health of eyes and all aspects of the body, and benefit others.
