What is a common method for preventing water from entering the mask?

A high-quality mask seal is crucial for preventing water from entering the mask while diving. The mask seal is the part of the mask that comes into contact with your face, and a properly fitted seal ensures that there are no gaps through which water can seep in. When the seal is effective, it creates a barrier that maintains a dry environment inside the mask, enhancing visibility and comfort underwater.

A well-constructed mask, often made from high-quality silicone, conforms better to the shape of your face, which significantly minimizes the risk of water intrusion. Regular checks for damage or wear on the seal, along with ensuring the mask is fitted correctly before diving, can help maintain its effectiveness.

The other methods, while possibly contributing to mask performance in different ways, do not primarily address the seal's integrity. Adjusting the straps may secure the mask better but does not guarantee that the seal will be effective if the mask itself is not well-fitted. Inhaling through the nose can help remove minor water that may have already entered but is not a method for preventing water from entering in the first place. Using anti-fog solution is designed to prevent fogging and improve visibility rather than to stop water from leaking into the mask.
