Public security universities have different vision requirements for candidates. For candidates who apply for ordinary batch admission, there are not many requirements for vision. Candidates who apply for early batch admission have a naked eye vision of not less than 4.8.

Therefore, if myopia surgery is performed after the college entrance examination, as long as the postoperative vision reaches the standard, you can apply for early batch admission to the public security university. For candidates admitted in ordinary batches, no surgery is needed, as long as they meet other conditions for admission.

It should be noted that it takes a certain recovery time after myopia surgery, and it must be six months after surgery without complications before you can apply for the exam. Therefore, if you want to apply for public security university, it is recommended to have surgery in advance so as to have enough time to restore your eyesight and prepare for the exam.

At the same time, you should also pay attention to other relevant physical examination requirements and standards when applying for public security university, so as to ensure that you meet the application conditions. If you have any questions or need more information about myopia surgery, it is recommended to consult a professional doctor or relevant institutions.
