Do I have to wear sunglasses when traveling to Hainan?

In fact, you don't have to be so entangled in this problem. First, you go to Hainan to wear sunglasses for sun protection and protective glasses. The sunshine on the beach is very strong. Secondly, swimsuits and sunglasses on the beach are also the best dresses for the beach. Hey, it's gonna be beautiful. Actually, it depends on someone. If your family is nearsighted, one is to choose contact lenses, and the other is protective myopia glasses, which can adjust the color according to the sunlight. But young people don't usually wear these glasses, which are more suitable for your parents. I hope they can help you.
