Introduction
Divers can see underwater due to the air-space created in front of the eyes, given that light is transmitted differently in the water than in air and the human eye can only focus when looking through air.
The mask is what creates such air-space in order to see well underwater. Masks have a space enclosing the nose which is absolutely necessary for pressure equalization to take place.
There are a great deal of models and brands on the market. Before choosing one, it is a good idea to know of the different types available and what features it should include to cover all needs.
- There are masks made of rubber or antiallergenic silicone. The main concern is that the mask fits well to the face and that the edges be soft so as not to irritate the skin, and at the same time firm enough so as not to let any water through.
- The straps should be easily adjustable and have clip or buckle fasteners in order to be able to change them quickly, should the need arise. It is advisable that the straps be made of plastic and not neoprene, as these can slip during the jump into the water, knocking off the mask.
- There are masks with 1, 2, or 4 lenses (in some cases lenses can be replaced by a prescription glass for those with sight impairment). – The lenses can be toughened or laminated lenses, which are less likely to cause sharp splinters in the event of their breaking.

Care and cleaning:In order to avoid as much wear and tear possible it is advisable to:
1. Wash mask with plenty of sweet water, even if it has only been used in swimming pools.
2. Avoid placing in direct sunlight.
3. Store in fresh, dry places.
4. Lubricate the joints with silicone at least once a month.
5. If the mask is not to be used for a considerably long period, store with a little talcum powder.
