Scuba Mask

YouTube Preview ImageYour vision when underwater is the second most important thing after your breathing. The human eye is not able to fully focus underwater so the scuba mask, also known as the diving mask, is made in a way to provide an air pocket preventing any water from coming into contact with your eyes. This enhances your vision and focus so you can see clearly underwater as if you were on land. The reason for the lack of focus without the scuba mask is that when the human eye is in direct contact with water, when compared to its normal environment in air, light entering the eyes refract by a different angle which makes the eye unable to focus the light. So by providing those air spaces, through the air pockets in front of the eyes, light is able to enter and focus normally.

Basic Construction

The basic mask scuba divers and recreational divers wear has a durable, tempered glass plate in front of the eyes. The reason for using tempered glass as the cover is because plastic will fog up easily and standard glass is dangerous if accidentally broken. This tempered glass is held by a "skirt" of silicone or rubber which creates a watertight seal on the diver’s face and a strap keeps the diving mask in place.

Masks that are being used at depths must have an enclosed nose type of construction so that the diver can exhale through the nose into the mask to prevent the “squeeze” caused by the increase in pressure when descending in water. That’s why your nose must be within the eye pocket so you can adjust for pressure changes and this is why normal swim goggles cannot be used for scuba diving.


Features to Check Out

Nose Pocket: One of the main purposes for the nose pocket is to better prepare your ears for the high pressures of the deep. They enable you to pinch your nostrils before diving, therefore, equalizing the pressure to your ears. Even though many divers prefer to use one hand to do this, many newer models require you to pinch it using both hands.

The Purge Valve: Located below the nose pocket, the purge valve allows you to get rid of water that leaks into the mask. This is done by gently exhaling through your nose to clear the mask of all water content keeping your vision clear at all times. This is a very handy feature as it not only vents out any water leaks but it also keeps your scuba mask clean. However, you can blow water out of the mask without the purge valve as well.

Field of Vision: Not all scuba masks provide a good field view when underwater. Side windows were created for various reasons including the ability to use your peripheral vision underwater and it also adds volume to the scuba mask. However, many divers find it difficult to focus through as the supposed better horizontal field it provides is offset when below the surface due to the water’s refractive effect.

Color: It may not seem like it but the color of your mask plays a very important role in your decision. Clear, light colored masks give you more peripheral vision as it allows more light in. Apart from this, the light color is also known to help overcome any feeling of claustrophobia and reduces anxiety for first-time divers. Black or other dark colored masks work best if you want to take underwater pictures as they block out extra light and side movements.

Other Tips

When buying a mask, scuba divers usually look for the strap adjustments with numbers on it as it easier to remember the preferred setting. Another thing to keep in mind is to never buy cheap scuba masks as there are things you can’t see, such as silicone and glass quality, that are just as important as the things you can see. Also test whether the scuba mask is a perfect fit. To this, hold the mask gently against your face without using the straps. Gently inhale through your nose and, if it fits, it will stay there without leaking and continuous suction through our nose.
