Conquering waves: the ultimate sunglasses for tide trekkers

With floating frame, precision, and seawater resistance lenses

Common issues with water sports sunglasses

Seawater Corrosion
Saltwater exposure gradually erodes lens coatings — particularly mirrored and polarized finishes — causing discoloration, diminished optical clarity, and reduced durability.
Sinking into Water
Many sport sunglasses lack buoyancy and sink immediately if dropped into the sea, making them difficult or impossible to recover.
Persistent Glare & Reflections
Even with polarized lenses, reflections from the uneven water’s surface can sneak through, disrupting clear vision. This is particularly noticeable during high sun angles or when light bounces off waves.
Fit & Comfort Issues
Sport sunglasses often face slippage due to sweat or seawater, especially during active use. Poor ergonomic fit can cause discomfort during long wear.
Digital Screen Visibility Problems
Polarized lenses can make digital instruments, GPS displays, and navigation screens unreadable or black out due to traditional polarisation technology.

Polarized

Polarized lenses are specially designed to reduce glare and improve visual clarity, particularly in bright outdoor conditions. They contain a chemical filter that aligns light waves, allowing only vertically oriented light to pass through while blocking horizontally reflected glare from surfaces like water, roads, and snow.
Benefits of Polarized Lenses:
Reduced glare: Helps minimize reflections from flat surfaces, improving visibility.
Enhanced contrast: Makes objects appear sharper and clearer.
Less eye strain: Reduces discomfort caused by excessive brightness.
Better vision in bright environments: Ideal for outdoor activities like fishing, boating, and driving.

Polarised

Polarised lenses are specially designed to reduce glare and improve visual clarity, particularly in bright outdoor conditions. They contain a chemical filter that aligns light waves, allowing only vertically oriented light to pass through while blocking horizontally reflected glare from surfaces like water, roads, and snow.
Benefits of Polarised Lenses:
Reduced glare: Helps minimize reflections from flat surfaces, improving visibility.
Enhanced contrast: Makes objects appear sharper and clearer.
Less eye strain: Reduces discomfort caused by excessive brightness.
Better vision in bright environments: Ideal for outdoor activities like fishing, boating, and driving.

Prescription

Prescription lenses are designed for individuals who need vision correction, whether for near-sightedness or far-sightedness. If you do not require corrective lenses, please select non-prescription sunglasses for the most accurate calculation.

Lens Materials:
1.61 Index optical-grade polycarbonate
Innate UV400 protection

Normal/Smaller

Our frames are crafted from an innovative material called FlexFoam™ — a lightweight, ultra-flexible, and soft compound that offers exceptional comfort and adaptability.
While we recommend them primarily for individuals with normal or smaller head sizes, FlexFoam™ unique adjustability ensures a secure and comfortable fit for a wide range of head shapes and sizes. Unlike traditional frames that require precise measurements, FlexFoam™ naturally conforms to your contours — whether your head is smaller or slightly larger than average.
