1, understand the policy: first, understand the relevant regulations of schools or military training institutions, and understand whether students are allowed to wear sunscreen masks. Usually military training institutions will provide uniform military training clothes and accessories. If you can buy your own sunscreen mask, you can consult the instructor or the person in charge.
2. Prepare certification materials: you are allowed to wear a sunscreen mask, and you need to provide relevant medical certificates or personal statements. You can go to the hospital to issue a diagnosis certificate stating that you are allergic to sunlight and need to wear a sunscreen mask. In addition, you can write a personal statement explaining why you need to wear a sunscreen mask.
