Scuba Mask
For scuba divers, most specifically the beginners, one of the more important piece of diving gear that they need to have is the scuba diving mask, which, in other references, is sometimes known as the scuba mask. This basic piece of scuba equipment allows divers the ability to see when swimming underwater, primarily through a glass plate located in the front portion of the gear. Scuba masks serve primarily as aids to the eyes when they are underwater.
This is because when the eyes get submerged in water, they are unable
to direct the light in its proper place since it is refracted at an unfamiliar
angle, basically because of a different environment, i.e., water. Scuba
masks simply provide an air vent for the eyes, allowing light to enter
in its normal fashion and eventually enabling the eyes to direct it properly. Of course, this will largely depend on the kind of mask used, and for this, the ideal mask is one that fits the face perfectly, eventually forming a seal. It should be noted, however, that most modern diving masks carry a silicone or a rubber content, a feature that ultimately produces a watertight hold on the face of a diver. Some scuba masks feature a single outlet valve located just beneath the nose which allows water to go out. In these types of masks, the diver holds the gear upright, then exhales nasally. In other versions, meanwhile, special valves keep the nose of the diver closed and serves the basic role of pressure equalizer as this builds up in the ears. When purchasing diving masks, priority should be given on whether it fits tightly on the face. A good way to determine this is by placing the mask onto the face without strapping it on. Without using the hands, try to keep the gear in place, then slowly inhale nasally. If the gear does not fall off, then most likely the gear will be an effective underwater equipment. On the other hand, if the process results in the mask falling off, then it is a sign that trouble can possibly take place once the mask is used under the sea.
