The fuzz of the seeds of French sycamore fly everywhere in the city. For allergic people, there will be a large increase in allergens in the environment, which can lead to the occurrence or recurrence of allergic eye disease. Typical is springtime catarrhal conjunctivitis, which is characterized by itchy, red eyes, tearing and mucus discharge from both eyes, and the appearance of follicles and staining of the lid conjunctiva. In order to prevent such diseases, patients should know which substance they are sensitive to and try to avoid eating or coming into contact with that substance. 2. Viral keratitis: Many patients with viral keratitis relapse in the spring and experience redness, eye pain, photophobia, tearing, and foreign body sensation after “catching a cold”.

Once you are diagnosed with pink eye, you must go to the hospital because the disease is highly contagious and can be easily contracted by healthy eyes that have been contaminated with the patient’s eye droppings or tears, so you must pay attention to personal hygiene. You should wash your hands before and after using eye drops and eye ointment, wash your face towels more often, and towels and basins should be used separately from your family to avoid infecting them. 4, the corneal ulcer: With the arrival of spring, many farmers are busy again, this time if the work in the farmland when negligence, it is easy to be branches, leaves and other scratched eyes, most people do not pay attention to this, think that the eyes are a little red after two days, in fact, this is not the case.
