1, corneal and conjunctival lesions: the cornea is commonly known as the black part of the eye, and the conjunctiva is commonly known as the surface of the white eye. Corneal conjunctiva because of microbial infection, physical and chemical factors that cause inflammation reaction often have eye stinging, grinding pain, acute phase is often accompanied by eye redness, eye boogers, fear of light, increased tears. In chronic inflammation, there may be only mild stinging or grinding pain in the eyes, and the conjunctiva of the eyelids may have stone formation. In this case only the inflammation or concomitant lid stones need to be treated.
2. Visual fatigue: This condition is common in people who work for a long time in close proximity, such as students, editors, writers and so on. Eye pain is usually sore, can't open the eyes, easy to tear, often get better after rest. If accompanied by refractive errors (e.g., hyperopia, astigmatism), a large difference between the refractive errors of both eyes, age-related decline in eye adjustment, wearing inappropriate eyeglasses is more likely to cause eye pain and fatigue. In this case, it is necessary to carry out accurate optometry, with a pair of suitable glasses (especially for close reading), and pay attention to appropriate rest, after resting the soreness and fatigue of the eyes can be gradually relieved. You can also try some eye drops with anti-fatigue effect to promote the improvement of symptoms.
3, supraorbital neuralgia: the cause of the neuralgia is unknown, because the supraorbital nerve innervates the upper eye socket and its surrounding skin, so the eye pain is often the orbital and its surrounding tingling, and part of the eyeball may have pain. This condition is characterized by significant supraorbital nerve pressure. Treatment may be symptomatic with analgesics to relieve the pain. Acupuncture and physical therapy are useful in relieving this nerve pain.
The above three kinds of pain are produced by excessive use of the eyes, it is recommended that the use of anti-radiation function of the glasses, sharp eye glasses effectively eliminate the external bad light magnetic wave damage to the eyes
