It is one of the easiest and most essential elements for diving. First, because without glasses we would be unable to distinguish the beauty of the underwater world and it protects us from direct contact with salt water.

There are two types of glasses. Those that are most used for recreational tank diving and those that are used more for apnea or freediving.

The difference lies in the volume of air they accumulate. Diving masks are usually more spacious with more volume since when descending slowly we have more time to equalize the mask (Remember that the mask must be equalized by blowing a little air inside so that it does not make us sucker with our eyes). Apnea masks, however, have less volume and it is so that when we descend quickly we do not feel the pressure so much and that it is easier to equalize since in this mode we must conserve as much air as possible. (in freediving it is also important to equalize the mask.




There is a wide variety of types and models of glasses, but the main thing is to choose ones that adapt well to your face to avoid the entry of water during the dive. For that, it is essential that the skirt fits perfectly to your face. The way to check this is difficult since stores do not usually have a bucket of water where we check that no water enters us. The most used way to test it is to put on the mask without the tape and breathe in through the nose, making a vacuum and checking that the mask adapts to our face . Bearded people have to bear in mind that not all masks will adapt to the beard. A trick for people with a beard is to put some petroleum jelly on the mustache before the dive.  

Our recommendation when choosing the mask is:  

If you have the opportunity and the luck of when you do your course or when you dive with a shop, to wear a mask  that suits you, ask for the make and model and try to buy the same.

If you are a traveler, you like  snorkeling or you also like freediving. If you buy a mask of this modality you can use it both in tank diving or in apnea.


Hollis M1


Visibility is the most important aspect of any dive. The M1 goggle raises the bar for optical quality and distortion-free vision. This lens is an extra clear glass that is valued for its attractive appearance and optical qualities. The low iron content produces higher light transmittance and a reduced green tint inherent in other glasses. This frees up lens distortion and helps improve color and visibility in low light conditions underwater.

Cressi Big Eyes

In this best-selling model, Cressi opts for transparent silicone that provides greater luminosity and that has a special treatment to minimize yellowing over time.


It has low fogging thanks to the fact that they do not contain silicon chloride. Its 15º angle of inclination of the crystals and its extension above the cheekbones (Big Eyes system) that increases the lower field of vision by more than 30% compared to conventional masks.

The buckles, completely pivoting in all directions and attached to the frame by means of a flexible elastomer. In this way, the tension of the strip acts directly on the frame, ensuring the stability of the mask and bringing the glass as close to the eyes as possible.

The extremely reduced frame structure also helps minimize internal volume, allowing you to compensate more easily.

This model also has the possibility of mounting graduated lenses, but only to correct myopia.



Very versatile and economical mask. With a reduced internal volume and a wide field of vision that make it perfect for both freediving and diving. Hooks positioned directly on the facial in soft Japanese silicone and in a backward position for greater hydrodynamics. The weight of the mask is particularly reduced. 

Highly recommended for small faces.



Revolutionary mask in the world of diving, thanks to the fact that it incorporates silicone earmuffs that keep the ears dry. Some ducts that connect the ocular-nasal cavity with the ear muffs, allowing easy compensation. Pro Ear has allowed people with hearing problems to dive ear such as external and internal otitis, eardrum perforations or compensation problems thanks to the isolation they provide from the ear canal. It is designed to counteract most of the unavoidable effects that pressure and water have on the ears and increase satisfaction under the Water.
