Scuba diving has now become a fashion, not only for the professionals but for individuals who do this as their leisure activity. Groups had been formed and friends bonded because of scuba diving which they do once a year or if they have the spare time. For professionals, they do scuba diving for underwater photography and civil engineering tasks such as oil exploration, underwater welding or offshore construction. Commercial divers are also employed to perform tasks specifically related to marine activities like naval diving, repair and inspection of boats and ships, salvage of wrecks or underwater fishing like spear fishing. Scuba divers are also great help when it comes to rescue mission for sunken ships.

Recreational diving has brought a lot of different people to various ship wrecks and oceans around the world. Their activities include cave diving, wreck diving, ice diving or deep sea diving. It is important that they have the complete and correct gear whenever they go to dive sites. Water has a higher refractive index than air that is similar to that of the cornea of our eyes. This makes the light entering the cornea from water being hardly refracted at all. This leaves the eye’s crystalline lens to focus light which can lead to hypermetropia. Diving masks and diving helmets and full-face masks solve this problem by creating an air space in front of the diver’s eyes. And because of the diverse activities that scuba divers must go through, it is very important for them to have prescription dive masks. Prescription dive masks come in various design, colors, and functions. There are models that are lightweight and have a wide field vision which is perfect for underwater photography. Prescription dive masks provide the maximum field view with its extra large lenses that give vision from edge to edge mask.

Silicone, a non-allergenic material which resists deterioration, is the most favored material for dive masks. Frames and buckles are made of hard plastic as oppose to using metal components because they are lighter and less costly, and will definitely last longer than the metal components. A lot of masks nowadays come with a second sealing surface like the double-flanged face to increase the air and watertight properties of the mask. There are masks that are suitable for the different size and shapes of faces for snug fit and easy clearing. There are dive masks that are described as low-volume. Low-volume masks have lenses that are closer to your eyes, so vision will be clear especially for underwater photography. Aside form giving a better peripheral vision, its decreased bulk gives less resistance, decreased distortion and enhanced light transmission through the water. But for prescriptions with higher plus or minus values, low-volume masks may be unsuitable. It is therefore important that you buy your dive masks from a company that will give your size and the suitability of every mask as accurately as possible like the DiveVision.

DiveVision also has a range of corrective swim goggles for divers with problems with their eyesight. Divers who wear glasses can now have the same good vision underwater as they have with their eyeglasses on land, with all the comfort, convenience and ease of divers who do not wear eyeglasses.
