In masks, there are two main types: single and twin lenses. Single lenses are composed of a single piece of tempered glass, creating a better view. However, single lenses cannot be changed out for prescription lenses or replaced if broken as twin lenses can. Due to the need for optical correction, every prescription snorkel mask on this list has twin lenses.

Buyer's Guide


Prescription Lenses

There are three main types of prescription lenses someone can order — nearsighted, farsighted and bifocal. Nearsighted optical corrective masks tend to come in -1.0 to -10.0 by 0.5 increments. Farsighted optical corrective masks usually come in +1.0 to +5.0 by 0.5 increments. Bifocal masks may come in +1.0 to +4.0 by 0.5 increments. When buying prescription snorkel mask, be very sure to read up on the specifics required by the dealer to get the necessary mask. Often, different values can be given for each piece of glass — one for each eye — but that needs to be specified in the manner which the seller requires. Make sure to comb the prescription snorkel mask reviews to find how a seller can meet diving and visual needs. Otherwise, a buyer may end up a mask they can only partially see out of at best, and not see out of at all at worst.

Field of View

The field of view (FOV) is the vertical and horizontal degree a specific mask allows you to see underwater. Rectangular or round lenses often increase horizontal FOV. An example of this type of mask is the Promate Optical Corrective mask. The other popular type of lens shape is an inverted teardrop shape with a raked design. A raked design allows the bottom of the lenses to sit closer to the cheek than at the top, which improves the downward view by making the mask bottom less visible. An example of this mask type is the IST Prescription mask.


After the prescription snorkel mask lenses, the fit of the mask is the next most important element. A great fit is crucial to keeping the mask from leaking and lenses from fogging. As such, a great fitting mask can help keep dives free from distractions, creating the best experiences possible to encourage further diving or snorkeling in the future. To know if the mask fits a face well, hold it up and align it to the nose without using the strap. Breathe in. If the mask holds to the face on the breath in, then that’s a good indicator that it will form a nice seal underwater.


Masks have two main frame types: framed and frameless. Frameless masks have lenses directly molded to the silicone skirt, streamlining the design while improving the ability to fold flat, usually creating low internal volume. This type of mask is popular with freedivers, especially. On the other hand, framed masks have a rigid framed form which is used as a backbone for the skirt, buckles, and lenses to attach to. Framed masks can often be fit with prescription lenses, which is why every prescription snorkel mask on this list has a frame.

Internal Volume

The internal volume of a mask is the amount of airspace inside of a mask when it is on a face. The more internal volume there is, the more air there is to be compressed when descending, leading to an increased need for equalization. A low-volume mask usually has the lenses close to the eyes, increasing FOV while decreasing internal volume. Freedivers and spearos use their held air to equalize so a mask having small internal volume is crucial to staying down longer for each breath. For example, the Tusa TM-5700 Liberator Plus is a low-volume mask.


The skirt is usually made from hypoallergenic silicone, which is soft enough to provide comfort and form to the face to prevent leaks. It is what keeps a person’s face dry while allowing them to equalize. Clear skirts, also called transparent skirts, are ideal for letting in more light to the eyes and decreasing any sense of claustrophobia a person may be feeling in the water. Meanwhile, opaque skirts, such as black, focus the view by minimizing distractions and glare. That’s why freedivers, spearos, and photographers tend to prefer dark opaque skirts over transparent ones.

Straps and Buckles

Another feature of a mask is the strap and buckle system. A mask strap should be able to stretch enough that minor adjustments can be made easily throughout a dive. Also, strap covers are recommended for divers or snorkelers with long hair which could tangle up in the strap. Another thing to check is that the strap buckles can be handled easily, even when wearing dive gloves.

Purge Valve Masks

To get certified, all divers should be able to clear their masks. However, some scuba divers simply don’t like doing it. The answer to that lies in a dive mask with a purge valve under the nose. These types of masks allow a diver or snorkeler to clear out a mask by blowing out of their nose. For example, the Promate Prescription Combo Set features a mask with a purge valve. Please note, however, that purge valves may clog or malfunction, resulting in a potential leaky mask.



One of the most common complaints people have about a mask is that it leaks. Often, it may be that the mask is ill-fitted. Make sure that the mask is formed for face type, whether the diver has a small, narrow or round face. This also applies to instances of high or wide noses and foreheads, which can cause discomfort in certain masks. Other than ill fit, another reason for leaks may be that there is a hair which has come under the skirt. Make sure to sweep strands away. For beards, try a mask with a smaller sub-nose seal. In general, loosening the mask strap can help with leaking as well as equalization problems.

Fog (New Mask)

New masks usually come with a silicone film acquired during the manufacturing process. To remove that film, use a soft cloth to rub white toothpaste in circles on the dry glass. Rinse, dry and repeat.

Fog (Used Mask)

Often, a mask may fog up due to body heat and humidity creating condensation. A popular means to de-fog a mask is to use treatment solutions such as a baby shampoo-water mix (baby shampoo won’t sting your eyes) or spit.


After a dive or swim, rinse the mask in warm freshwater and let it dry completely before packing it away. Make sure not to bend or squash it in storage, or it could lead to skirt disfigurement or frame distortion – neither of which are good for the durability of the mask. Also, make sure to regularly check the skirt, straps, and buckles for signs of fine cracks. If spotted, replace that part immediately. If that part cannot be replaced, then it is time for a new mask.
