How to deal with red eyes must depend on the cause of the redness of the eyes. If the eye redness is accompanied by significant tearing, foreign body sensation, and more white eye droppings, viral conjunctivitis caused by a viral infection may be considered. It needs to be treated with antiviral medication, using ganciclovir gel or acyclovir drops for antiviral treatment. If there is a lot of yellow eye stool with redness of the whites of the eyes, especially in the early stage, the stool is stuck on the eyelids and affects the opening of the eyes. Consider bacterial conjunctivitis caused by bacterial infection and use levofloxacin or tobramycin drops for anti-inflammatory treatment. If the eyes are slightly red, with edema of the whites of the eyes, or itchy eyes, it may be allergic conjunctivitis caused by allergies. Anti-allergic treatment with Olopatadine drops or Flomipron drops may be considered. If the eye is red and painful, with congestion mainly in the black and white areas of the eye, it may be a case of iridocyclitis and may require hormonal eye drops.
