Choosing regular corrective lenses or bifocal for your Tusa Freedom Ceos mask:

Negative corrective lenses are for anyone with near-sighted or myopic vision.These lenses are beste for divers who need glasses to see anything nearby clearly.

Positive corrective lenses are for anyone with far-sighted vision. Theses lenses are best for divers who normally wear glasses to see better in the distance.  If you can see things nearby, your camera and gauge, but things in the distance aren’t clear, these lenses are for you.

Bifocal lenses are for gauge reading and for divers who need both distance and near correction at all times. If you usually wear multifocal or bifocal lenses in your everyday glasses, order bifocal lenses for your mask as well.


Corrective lenses are available in 0.5 diopter increments. Choose the correct strength for your left and right eye in the drop down menu.

Available corrective lenses:
-1.0 to -8.0 and +1.0 to +4.5

Freedom Technology:

Each person has a unique facial structure and every diver can potentially experience some level of discomfort or “pressure” while wearing a typical mask underwater. TUSA engineers wanted to solve these problems and spent several years analyzing mask fit, facial bone structure and mouth movement. The result is Freedom Technology, a set of revolutionary new mask features delivering superior fit, comfort and increased performance. Experience Freedom.

Freedom Fit:

Freedom Fit offers a superior fit and level of comfort by utilizing three specific design features.

Dimpled Skirt:

Key areas around the forehead and cheek bones have been designed with dimples which combine to increase the skirt’s softness, flexibility and skin surface contact. This also greatly reduces leakage and enhances comfort.

Varied Silicone Thickness:

A regulator or snorkel mouthpiece, when in use, can cause areas of the mouth and nose section to distort causing leakage and discomfort. Varied thicknesses of silicone in these key areas reduce leakage and provide a better fit.

Stability Ridges:

As water pressure increases, a mask will compress inwards toward the face often causing further leakage or discomfort. Areas under the cheek bones have been reinforced with stability ridges to minimize this compression maintaining ideal skin surface contact.

Freedom Dry:

Freedom Dry enhances comfort and fit by utilizing a revolutionary low friction skirt surface. The skirt fitting line (shown in red) includes a low friction surface that delivers a superior seal and increases the facial area contact patch while significantly reducing excess skin tension. The result is a soft and supple feeling mask with a dramatically improved seal.


In addition to Freedom Technology, the Ceos features:

  • TUSA’s patented Quick-Adjust Buckle System,
  • 3-D Anatomical Strap,
  • Round-Edge skirt technologies and
  • also available in a PRO version (M-212S) with CrystalView optical glass lenses treated with a proprietary anti-reflective (A/R) and ultraviolet (U/V) coating.




Please allow 3 extra days for shipping as we need to custom fit your lenses into the mask frame.
