1) why do we need to take a mask to look at the view of the bottom? That is because our eyes need some space to focus on see things. Snorkeling mask and diving mask is basically the same, except the shanzhai snorkeling mask.

2) whether have myopia have to with a degree in front of the mirror? Because the cause of the light refraction, the bottom of things than on the surface looks nearly and big. So ordinary mask in the water will be on your own degree plus 100 degrees for you. Generally a little degree friend common in front of the mirror. If a high degree, such as 300-300 degrees, even on the emission, hey hey, you can ask in advance to go holiday village, or hotel have the rent has a degree in front of the mirror. But I personally feel, general seaside resorts, is not to prepare many prescription in front of the mirror. Each degree may be a few pairs, one to the busy season is estimated to rent.

3) in addition to a degree in front of the mirror, still have what way? Wear contact lenses. It is best that day type. This is more convenient. A lot of people care about contact lenses will fall off when diving, this situation is rare. Unless you are in front of the mirror not to cover your face. When the water will suddenly filled with water. But the general water is first to your nose. This time you look up if snorkeling early, so stealth won't fall off, can be at ease wearing. If you encounter a situation off, because the Japanese type will not bring you great losses, with another line. Some people say is not used with contact. But when you see the beautiful underwater world, estimates that uncomfortable early is forget by you to the moon. Learn diving friend is different, you are at the bottom is to practice your mask drainage technique. This time you have to turn your coach, and see if I can arrange to do you have a degree in front of the mirror. If not, your coach know you have my contact lenses, they will teach you how to use. What to wear glasses in the inside of the mask idea or saved. Not possible. Have my contact lenses is one of the most simple way.

4) how to avoid the uncomfortable when wearing a mask? Snorkeling or diving on the face is best not to rub sunscreen. Even if they wipe should go out at least half an hour ago. Let the sunscreen is completely absorbed into the skin. Or sunscreen would slip, mask will suck your face. It is best not to wipe. Second, suntan lotion contains heavy metal elements, after hydration to your eyes is the pain you enough, sometimes the eye is swollen.

5) the water in my eyes will pain? Friends can have a try next time, the whole eyes open into the sea, then look up, you won't feel eyes hurt. Seawater instead bit by bit in the eyes can let an eye very not accustomed to. But after a few times was no problem.

6) how can avoid the water of the sea in mask? Wear a mask when don't bring the hair in the mirror, wearing a good after the hair to mirror outside. Mask as far as possible with down and completely cover the nose. If your belt is too high, the breathing tube down in the mouth, mouth a drum, mask to loose, you half a nose may be in the water. So remember to take down as far as possible, do not cover your lips. (boys can try to put the beard shaved). Firmness and mask, best adjust both sides to adjust tightness beforehand, so more convenient and more accurate.

7) how to don't let the mask of fog? Newly purchased under the mask had better use lighter to burn a mirror inside. You don't need to outside, because the new mask will have a layer of wax. Burn care as far as possible, don't burn to the inside of the plastic, burned out you bought again. If not sure call experienced help. You can also use toothpaste with washing the dishes with the sponge wiped a few times more. After wash. Breath iced into the mirror and see to have fog, so wash again. But some fake page mirror do hard to wash, has the time people use lighter to burn for a long time or not, and mask is not cheap. So you'd better buy more prominent in front of the mirror. Put out to sea before, can put the toothpaste evenly daub on the mask layer, lay, to at the end of the water and then wash with water. There is no toothpaste use shampoo shampoo can also. Don't really have words with saliva, although not elegant. But don't wash out after finish vomit saliva, direct put on, will be more effective. Don't often wear a mask, use you wear a few times, and fog slowly mask. No need to try not to take down after wearing. If there is water, looked up and open the mask below water away.
