Yellowing of the whites of the eyes due to conjunctivitis can usually be restored to whiteness. Conjunctivitis is usually caused by infections and immune disorders, and patients may experience symptoms such as a foreign body sensation in the eye, photophobia, and increased discharge. Due to the stimulation of inflammation, the capillaries within the conjunctival tissue may be dilated, so the conjunctival tissue on the surface of the eye looks yellow. The whites of the eyes will usually return to white naturally after the inflammation subsides with aggressive anti-infection treatment. To treat conjunctivitis, antibiotic eye drops, such as ofloxacin eye drops and tobramycin eye drops, are required. If it is caused by immune or allergic factors, it can be treated with medications such as flumethasone eye drops and tobramycin dexamethasone eye drops. During the treatment period, attention should be paid to maintaining eye hygiene and not rubbing the eyes to avoid aggravating the infection. Patients with conjunctivitis should consult a doctor in time, follow the doctor’s instructions to standardize the treatment, and the drugs need to be used under the guidance of the doctor.
