Symptoms of chronic conjunctivitis vary depending on the cause, individual variability, and severity of the condition. Depending on the condition and course of conjunctivitis, it can be divided into three categories: acute, subacute and chronic. Symptoms of conjunctivitis commonly include red eyes, itchy eyes, foreign body sensation, burning sensation, heavy eyelids, increased secretions, photophobia, tearing and varying degrees of vision loss when the lesion involves the cornea, and possibly edema of the eyelids. Not all of these symptoms are present, nor are they uniform in degree. Chronic conjunctivitis is a type of conjunctivitis that has a long and persistent course and is a chronic inflammation of the conjunctiva caused by a variety of factors, including bacterial infection, environmental irritation, and poor lifestyle habits. It is characterized clinically by foreign body sensation in the eye, itchy eye, white foamy discharge, red eye, dry eye, sometimes mild and sometimes severe, but the symptoms cannot disappear completely. Chronic conjunctivitis can be cured, but the key is to find the cause of the disease, and after a clear diagnosis, targeted treatment. In addition, improving your daily habits can be helpful in curing chronic conjunctivitis, such as washing your hands with warm water and soap, and not sharing eye water or eye ointment with others. When the eyes are red and swollen, it is not advisable to wear corneal contact lenses and eye makeup, and to seek medical attention once the eye infection is found to be aggravated.
