How to dive for myopia?

First, check the fundus and myopia before diving. As long as the fundus is healthy and there are no cracks, diving and skydiving can be carried out smoothly. Testing myopia is used in conjunction with diving glasses. Because the refractive index of the seabed is not filled, the degree is actually quite fresh. Let me give you an example of myself. I am nearsighted 1000 degree astigmatism 150. My diving goggles are 800 degrees without astigmatism, and I can see clearly at the bottom of the sea, no problem. However, try the mirror yourself. It is important to cover the mirror, because it is not easy to get into the water. Secondly, novices or people who want to learn OW should not try to wear contact lenses. I don't know why so many people in Zhihu say that diving with sun-throwing contact lenses is no problem and there is no pressure. I think it is very dangerous and even fatal for beginners and students with high myopia. First of all, when the mirror drains during the OW test, there will definitely be water entering the eyes, and the eye pain will not be mentioned. It is very likely that the contact lenses will be washed away by seawater. Therefore, novices are very prone to panic, and they can't see the panic fluttering at the bottom of the sea, which is easy to cause an instantaneous rise. That will make my lungs explode. I was lucky to have a coach when I took the OW exam. Because the mirror drainage was not done well, I panicked, spit out the respirator and rose urgently. If the coach hadn't hugged me hard, I might have exploded. Secondly, the sanitary conditions on board are generally not very good, and the sea surface is shaking. If you are not a master at picking contact lenses, how can you wear them on the boat? Usually dive three times a day, and each dive is ice and snow. Eat and drink quickly, have a rest, and then dive immediately. There is little time to get glasses. Even if you move quickly, worrying sanitary conditions can easily make your eyes inflamed. So in order to have a pleasant trip, spend hundreds of dollars to get a mirror with a degree. Finally, if you are a friend who usually wears frame glasses, it is recommended to bring a glasses case to prevent the glasses from being accidentally pressed into the bag after changing the glasses. But some thoughtful captains will help you hang your glasses on the bow. But you can't ask the captain of every ship to be so considerate. Prepare a box for yourself. Just sauce. Eyes are the windows to the soul, and life is precious. Protect yourself, get ready and dive safely. Diving is not a very safe sport, and I almost died because of diving. So I was filled with emotion and verbose. Take care.
