For the sake of safety, you had better take your dad to the hospital to ask the doctor to prescribe some medicines for your dad. The doctor may prescribe some antibiotic eye drops or oculentum for your dad to apply into the eyes every day, three to four times a day. And some oral antibiotics may also be prescribed to your dad to help get rid of the eye stye. You should pay attention not let your dad overuse his eyes, instead, he needs adequate rest and good eye hygiene. Apply a warm water dag or a piece of warm towel onto each of his closed eyes for about ten minutes every day so as to help the blood circulation in his eyes. Supplement vitamins and minerals for his eyes by adding vegetables and fruits to his daily diet.
