The application conditions vary from place to place. Guangzhou's application condition is that as long as you are 22 years old and have an intermediate certificate, you can apply for a senior optometrist. You can apply at Guangzhou New Pearl River Glasses School. There are four days of training before the exam. Theory is a multiple-choice question and a true-false question. Practical examination includes comprehensive optometry, examination, slit lamp and calibration. I was admitted to the senior optometrist of that school in April, and I heard that all the students were admitted.
