The TUSA MC-211 Corrective Lens is a premium, high-precision optical replacement lens engineered to restore sharp underwater vision for scuba divers and snorkelers requiring vision correction. Designed exclusively for advanced dual-lens configurations, these lenses are completely interchangeable and can be seamlessly installed into the left or right sides of the TUSA M2004 Intega and M-211 Freedom One dive masks. Providing precise spherical correction, they offer an efficient, custom solution to eliminate the need for contact lenses underwater, ensuring uncompromised optical safety and clarity on every dive profile. Corrective Lens Features Single Lens Packaging Note: Lenses are sold individually per side (not in pairs) to allow for completely asymmetrical prescription matching Advanced Freedom Frame Insertion: Engineered to integrate perfectly into TUSA's high-end dual-lens chassis, specifically optimized for the M2004 Intega and M-211 Freedom One series Dedicated Spherical Correction: Provides highly accurate, non-astigmatic visual correction across a comprehensive range of focal distances Broad Diopter Selection Matrix: Available in precise half-diopter increments spanning from negative myopia corrections to positive hyperopia corrections Bifocal Reader Availability: Offers specialized reading panels at the base of the lens, allowing divers to clearly scan dive computers, gauges, and macro camera screens Prescription Range & Compatibility Matrix Lens Type / Application Diopter Range Options Increment Step Negative Lenses (Nearsighted / Myopia) -1.0 to -8.0 0.5 Diopters Positive Lenses (Farsighted / Hyperopia) +1.0 to +4.5 0.5 Diopters Bifocal Gauge Readers (Presbyopia) +1.0 to +4.5 0.5 Diopters Important Ordering Note LENSES SOLD INDIVIDUALLY (Select Quantity 2 for a Pair) Verified Mask Compatibility TUSA M2004 Intega / M-211 Freedom One Technology SPHERICAL GROUND OPTICAL TEMPERED GLASS The MC-211 lenses are formed from ultra-clear tempered glass that has been ground to exact spherical technical specifications. Tempering ensures maximum structural pressure-resistance at depth while providing elite scratch immunity compared to standard polymer alternative lenses. The advanced optical purity minimizes refractive distortion under water, delivering true-to-life spatial tracking. INTEGRA & FREEDOM CHASSIS COUPLING The geometric perimeter of the MC-211 is precision-molded to match the high-performance lens retainers of TUSA's flagship mask lines. Whether seating into the low-friction skirt of the M2004 Intega or the structural reinforcement frame of the M-211 Freedom One, the edge profile seats flush against the internal sealing ring, completely eliminating water ingress under high ambient pressure. INTEGRATED LOWER-QUADRANT BIFOCAL READER For divers experiencing presbyopia, the reader variant features a split focal field. The top portion of the lens remains uncorrected for long-range environmental awareness, while the lower segment integrates a localized positive magnifying block. This arrangement allows for seamless transitions between checking instrumentation data, reading a bottom timer, or navigating tight interior wreck corridors without breaking stride.

III) The AWLS III features an upgraded single-locking integrated weight mechanism that simplifies balance adjustment. Divers can seamlessly load ballast into the removable cartridges and slide them effortlessly into the jacket housing. A positive mechanical click guarantees a secure lock, while the quick-release handles permit fast, clean weight dropping in an emergency. ULTIMATE STABILIZING HARNESS (U.S.H.) TUSA's exclusive Ultimate Stabilizing Harness brings the cylinder closer to your center of gravity while entirely eliminating horizontal tank roll. Utilizing ergonomically placed alignment rails and a rugged backplate structure, it splits the tank's burden evenly across the hips, optimizing trim and boosting underwater attitude control. RITETITE BUCKLE TANK STRAP The RiteTite Buckle is an innovative two-position cam assembly that dramatically streamlines cylinder installation. As the webbing strap is routed through the path, the tension system automatically maintains its friction position without needing manual holding. This prevents slippage, increases structural safety, and delivers a highly stable lock against the tank.

The core structural design of the Soverin Alpha isolates the internal backpack and tank retention straps completely away from the buoyancy cell. Because the harness supports the tank independently, air cell inflation expands outward without squeezing your torso. This prevents cylinder shifting, preserves a snug fit at depth, and maintains ideal lumbar posture regardless of inflation state. ADVANCED WEIGHT LOADING SYSTEM III (A.W.L.S. III) The integrated AWLS III mechanism provides effortless ballast distribution with a streamlined single-locking interface. Lead blocks fit cleanly into the ergonomic weight pouches, sliding effortlessly into the integrated side receptacles of the jacket. An unmistakable tactile engagement confirms the locked state, while an intuitive pull-to-release design enables swift emergency deployment. ULTIMATE STABILIZING HARNESS (U.S.H.) By using a rigid, low-profile backing plates combined with precisely positioned stabilizer track rails, TUSA's USH framework locks the scuba cylinder rigidly along your spinal line. This brings the center of mass closer to your body, converting unstable tank roll into unified bodily balance while boosting buoyancy control during tricky lateral tracking maneuvers. RITETITE CAM STRAP BUCKLE This heavy-duty two-position cam buckle simplifies securing the BC to a cylinder. When looping the high-tensile webbing through the open gate, the buckle self-locks under tension without requiring active manual holding. This prevents webbing slippage, saves your fingers, and allows you to apply maximum mechanical leverage for a rock-solid hold.
