All masks aren’t created equal. Here’s how to find out if single-, dual- or tri-lens masks are for you.
Single-lens masks provide an unobstructed view of the underwater world. Because there is no solid nose bridge dividing the front window, you can look off to the left or right without losing binocular vision. This can also be a big plus when looking straight-on at close subjects.
Dual-lens masks tend to position the viewing glass closer to your eyes, which can increase field of view. They are the best masks for installing prescription lenses (some manufacturers offer low-priced drop-in corrective lenses that come pretty close to many divers’ actual prescriptions).
Three- and four-lens masks make use of side windows to increase peripheral vision as well as to let in more light, contributing to an airy feel — good for divers prone to claustrophobia. However, the intersection of front and side lenses, while producing a seamless joint when wearing the mask in air, creates blind spots and distortion at depth. Some divers think it’s worth it to be able to see what’s on their flanks, but for others, the distortion is too much of an aggravation.
