Eucalyptus oil is a kind of fluid of colorness or faint yellow, which is usually used to make up cough reliever, mouth wash or essences such as those of toothpaste or candies. You should wash your eyes with clean and flowing water to make the eucalyptus oil out of your eyes. After that, you can use some antibiotic eye drops into your eyes. Pay attention to have good and adequate rest and sleep. After two days of using the eye drops, then you can turn to use some erythrocin eye ointment for your eyes. Then after another two days, if there are no uncomfortable feeling in your eyes, you may set your minds at rest. Just remember that do not put something like this into your eyes in the future. However, if you still feel bad in your eyes after having taken the above measures, you had better go to the doctor's for an eye examination in case that the conditions turn worse.
