However, if there are special needs, such as unbearable naked eye test, or really need to wear contact lenses to function and work normally, you can consult a doctor or relevant staff in advance. Before consulting them, you need to provide them with your detailed information, including your history of eye diseases, the type of contact lenses you use, the wearing time and so on. In this way, they can better provide you with guidance and advice.
Generally speaking, it is a better choice to apply for a health certificate without wearing contact lenses if conditions permit. However, if you really need to wear contact lenses, it is best to consult doctors and related personnel in advance to ensure that the health certificate is handled smoothly.
