First of all, you should use clean flowing water to wash the lacquer thinner out of the eyes. Then you fill a washbasin with clean water, and dip your head into the washbasin to let your eyes be soaked by the water. And then you use your hands to open your eyes and rotate the eyeballs so as to clean the eyes as well as the eyelids and so on. After doing this, you should use a clean towel or a piece of facial tissue to wipe dry your face and eyes. With all theses done, you should go to the doctor's for medical treatments, because ther may be some poisonous chemicals in the lacquer thinner which can still damage your eyes after cleaning. The doctor may prescrib some antibiotic eye drops or oculentum for you. Besides, you had better wear a pair of sunglasses when you have to go out in the open on a sunny, in case that you eyes get irritated again by strong lights or polluted air.
