Antibacterial drugs such as levofloxacin eye drops and erythromycin eye ointment can be used for treatment under the guidance of a doctor. 3. Foreign bodies in the eye: If there are foreign bodies such as conjunctival stones or small bugs in the lower eyelid, they may cause irritation to the eye and cause lower orbital pain , which is induced or aggravated by friction when blinking. You will usually feel a foreign body in the lower eyelid, or turn over the lower eyelid to see a yellow-white, black, or other colored dot. Going to the hospital to remove the foreign body in this case can usually relieve the pain, and because the eye is more fragile, it is not recommended to remove the foreign body on your own; 4.

In addition, involvement pain can also occur during sinusitis or cold, which may act on the lower orbit and cause the symptom of lower orbital pain with a blink, requiring a visit to the ear, nose and throat department for treatment. It is important to take good care of the eyes on a daily basis, such as keeping a certain distance when looking at things, paying attention to eye hygiene, eating more foods that are good for the eyes, such as blueberries and carrots, and looking into the distance more often.
