I graduated from this major for 3 years. First of all, it depends on your diploma, but also on your school. If you are an undergraduate, and you are from one or two schools, you have a better chance of entering the hospital, or it is related. If you are three years old or a junior college student, you can only sell glasses in an optical shop or optometry in a private hospital. If you are a hospital, public hospitals recruit optometrists outside the establishment. I'm not tired at work. I work around 3000 in Chongqing. Private hospitals will be more tired if their benefits are good. I have a classmate who works 28 days a month, 9- 10 hours a day, with an average salary of about 3000. If the benefit is not good, it will be around 2000-2500. The optical shop is very tired and timid, one month 1500-2000. If it is a master's degree or above, it is still possible. If the scope of work can be optometrist, ophthalmologist, strabismus and amblyopia trainer, or with solid professional knowledge, you can be a trainer in an optical company. If you are a girl, not bad. If you are a boy, you can open your own shop if you have the financial conditions. Otherwise choose another major! I can't support myself with those two or three thousand dollars.
