Freedom Technology is a set of technologies to enhance fit and performance exclusive to TUSA. Freedom model masks feature a dimpled skirt surface with varied silicone thicknesses and stability ridges in addition to a proprietary low-friction skirt surface on the fitting line. The new Fit II technology adds strength and rigidness to the skirt for use in tough environments.
FREEDOM TECHNOLOGY
Freedom Technology is a set of technologies to enhance fit and performance exclusive to TUSA. Freedom model masks feature a dimpled skirt surface with varied silicone thicknesses and stability ridges in addition to a proprietary low-friction skirt surface on the fitting line.
TRI-MIX FRAME
Three (3) distinct layers combined to produce one superior frame structure. Polyurethane (PuRiMaX) material bumper protection and a cross-beam metal frame structure combined with the superior toughness of the polycarbonate frame bolted together to create a seriously tough mask.
UV 420 LENS TREATMENT
UV 420 Lens Treatment protects against harmful high-energy visible (HEV) light and its potential to damage the Retina. HEV light is not just present on sunny days, but overcast days as well. Therefore, it is extremely important to protect your eyes against UV and HEV light in all weather conditions when diving.
3D MASK STRAP
TUSA's patented 3D Strap is a true three-dimensional design that snugly fits against the head's natural curvature. The 3D strap offers unprecedented comfort and fit, unlike standard flat mask straps.
ANGLE STRAP ADJUSTOR WITH SIDE HOLD
The Skirt Mounted Five (5) Angle Strap Adjustor allows for a five position micro-adjustment on both the left and right sides of the mask. This enables vertical (up/down) and horizontal (left/right) pressure on the face to be delicately adjusted for the optimum fit.
ANTI-REFLECTIVE (A/R) LENS TREATMENT
TUSA's Anti-Reflective (A/R) Lens Treatment decreases internal and external reflected light. This reduction increases light transmission to 95% resulting in significantly enhanced color, clarity, contrast and better overall vision underwater.
CRYSTALVIEW OPTICAL GLASS
CrystalView optical glass lenses provide superior clarity, color, and transmission of light over standard glass lenses used by the competition. Up to 15% of available light can be lost with a standard glass lens due to impurities and reflectivity. TUSA's CrystalView lenses transmit up to 95% of available light to the diver for clear crisp vision. CrystalView lenses are used in all PRO models masks.
QUICK-ADJUST BUCKLE SYSTEM
The Quick-Adjust Buckle System incorporates a newly-designed low-profile buckle. The result is a compact, lightweight, technologically advanced mask design that can be easily and quickly adjusted for a perfect fit.
ROUND EDGE SKIRT
TUSA's Round Edge Skirt features a proprietary round edge cross-sectionally shaped skirt. This rounded edge results in a soft fit that suppresses pressure and reduces creasing left on the face. The "planar fit, instead of linear fit" silicone skirt maintains great fit and unprecedented comfort.

How To Order
Step 1 - Choose Your Mask & Lens
Visit our Prescription Dive Masks page to view our full range of masks. On each of our masks you have the option to add the lens corrections to your order. Simply choose your favourite, add the lens correction and checkout online.
If you already have a mask we are more than happy to bond prescription lenses to a mask you supply to us - provided the mask has tempered-glass faceplates. This can be a new mask sourced from your local dive-centre or dive-shop, or a mask you are already using. Simply choose the 'Supply Your Own Mask' option from the shop.
Step 2 - Upload your Prescription
Next please send us a copy of your prescription. You can:
Scan / take a photo on your mobile phone and e-mail a copy to: [email protected]
or
Photocopy and post to Dive Sight LTD, Unit 3, Carlisle House, 99 Carlisle Street East, Sheffield, S4 7QN
Please ensure that your opticians name and address are clearly visible on the prescription.
Please note that due to regulations we are unable to supply prescription masks if you are registered blind and we cannot supply to anyone under 16 years of age. Dive Sight is a professional optical service and we are not here just to sell you a prescription dive mask, we are here to optimise your underwater vision and maximise your diving pleasure. To do this, we need to be absolutely certain that the prescription details you provide are completely accurate and less than two years old.
It is very important that we have your precise prescription details and ophthalmic regulations require us to see a copy of your actual prescription form. Ideally, we need to see this at the time the order is placed.
This can be scanned and e-mailed, or sent as a hard copy. Address details are shown below. This is to safeguard your interest, as your mask will be custom-glazed and cannot be offered for resale. We are required to see a copy of the prescription prior to dispatching your order.
If you do not fully understand the information on your prescription or have any queries relating to your prescription just call us on 0114 3273140 and we can answer any questions you have.
Step 3 - Upload your Pupil Distance
Last, but not least, we will need a very simple measurement, to ensure you get the very best results from your prescription mask. This is the measurement of the distance between your pupils, (your PD) when looking straight ahead.
An accurate PD measurement enables us to position the optical centres of the lenses exactly in-line with the centres of your eyes, to ensure maximum visual comfort. This measurement can be obtained from your optician or you can either use a mirror to take the PD measurement yourself, or get a friend to assist you. The easiest way is to take a piece of firm card and hold it below your eyes and then make a pencil mark directly in line with each pupil and measure the distance between the two marks in millimeters (mm). A typical adult measurement will be between 58 and 70mm.
As eye care professionals Dive Sight ltd will not work to “approximate” values. We will produce your mask to your precise prescription to ensure we achieve the optimum visual acuity, making your vision underwater as good as it is on dry land. All our prescription lenses are made from optical glass, which minimizes distortion, reduces fogging and offers maximum scratch resistance. The corrective lenses are permanently bonded to the inside of the mask faceplates.
If you are unhappy with your purchase, we will take it back and refund the cost of the mask, but we cannot reimburse you for the cost of glazing as the lenses we fit are custom made to your specific prescription, and cannot be reused.
All Dive Sight masks are custom made to each individuals precise prescription, and carefully checked at every stage of production. As such, customers need to allow 28 days for delivery from receipt of initial order. In the event of your chosen mask being out of stock or unsuitable for your prescription, we will contact you and advise on alternatives.
Lens Options
Lens Materials
All our dive-mask lenses are made from optical glass, which minimises distortion, cuts down fogging and offers maximum scratch resistance. The corrective lenses, to your precise prescription, will be permanently bonded to the rear of the mask’s original flat ( plano ) glass, though, in cases of very high prescriptions, they may be bonded to the front surface.
Plus lenses
These are used to correct ‘long-sightedness’ ( Hypermetropia ) This describes the condition when distant objects can be seen clearly but near objects are blurred. The higher the power of a plus lens, the greater the effect of ‘tunnel vision’. This can necessitate a special choice of lens for higher + powers.
Minus lenses
These are used to correct ‘short-sightedness’ ( Myopia ) This is when near objects can be seen clearly but distant objects appear blurred. The higher the power of a minus lens, the thicker the lens edges become, giving peripheral distortion’. This sometimes requires lenses to be made to a specific size or in a specific material.
Cylinder
The 'cylinder' value of a lens is used to correct astigmatism, the condition where one part of the eye has an irregular curve ( instead of being round, it is shaped more like a rugby ball ). To further complicate matters, astigmatism may also occur at an angle ( this will be the case if you have an ‘axis’ value on your prescription.) If these problems are not corrected your eye cannot compensate, other than to a small degree, so your vision will be distorted and blurred. The only way to achieve correction is by using lenses with a cylinder value. 'Off the shelf' lenses do not have any cylinder correction. This is one of the reasons why we do not recommend their use.
Bifocal ( Read add )
As we get older, usually starting around the mid 40’s, the mechanism that allows the eye to focus ‘up close’ becomes increasingly less efficient and ‘reading glasses’ become a necessity, even though other spectacles are not generally required. Obviously this can present a problem when diving, as some correction will be needed to read gauges, or observe small objects without touching a delicate environment, such as a reef. To address this issue, we can supply masks with 'bifocal' lenses, whereby plain lenses or distance prescription lenses have a small, reading lens segment incorporated into the lower part of the lens.
Precise Prescription - Optimum Vision
DiveSight is a professional optical service and our primary aim is to give the underwater vision you need in order to get the optimum satisfaction and enjoyment from your diving. Any mask supplied by us will be glazed to your exact prescription. We do not use 'off the shelf' lenses with the nearest, approximate power, as is often the case with other websites that offer 'prescription lenses'.
Dioptres
The ‘power’ of the spherical and cylindrical correction ( your prescription ) is measured in dioptres. Ready-made, 'off-the-shelf', ‘prescription’ dive masks or swimming goggles, have lenses which come in 0.5 dioptre increments. As a result, they will only be to the nearest approximate power to your prescription, relying on your eye’s flexibility to try and adjust for the uncorrected error. Moreover, these lenses only correct the spherical part of the problem, with no correction for any cylindrical (astigmatic ) element of the defect. In order for us to supply you with the correct lenses, it is essential that the prescription information you give us is totally accurate and up-to-date.
If you are unhappy with your purchase, we will take it back and refund the cost of the mask, but we cannot reimburse you for the cost of glazing as the lenses we fit will be to your specific, personal prescription and the mask cannot be offered for resale with these lenses fitted.
