When divers choose a new scuba mask, they should consider the various available features. Standard masks have a tempered-glass lens to withstand the increasing pressure of a deep dive. However, some masks have two or more lenses.
Single-lens masks offer a wide view and good depth perception. The dual-lens variety offers a lens for each eye and allows divers both a horizontal and vertical view. Multiple-lens masks let in a large amount of light and offer the broadest field of view.
In most cases, single-lens masks work well for divers who have normal vision and are not claustrophobic. If a diver feels claustrophobic in a single-lens mask, he or she should try a duel- or multiple-lens mask.
Beyond the lens, certain masks have buckle/strap systems that are complicated and difficult to use. Look for a mask with a simple buckle/strap to ensure you will be able to adjust the fit with ease when you're in the water.
A mask with a good fit should seal out water, but many high-quality masks may not be able to keep out all the water. Look for a mask with a one-way purge valve that clears water from the mask when the seal is less than perfect.
