LENSES

The main reason we wear sunglasses is to protect our eyes from the effects of UV radiation, but there are additional reasons we wear sunglasses on the water – such as impact protection and the reduction of glare (reflections). High quality specialised watersports lenses not only offer optimal protection from UV radiation, their filtering capabilities can also significantly improve the quality of our vision.

UV BLOCKING

UV-blocking-lenses

UV blocking sunglasses lenses offer optimal eye protection, significantly reducing the risks from UV exposure. Like sunscreen, they should be worn as soon as you are outside, even on hazy / cloudy days as clouds do not block UV rays and surfaces like water, sand and buildings reflect it.

IMPACT RESISTANT

impact-resistance

The FDA regulates eyewear products to ensure their safety credentials. Impact resistance is an essential criterion that is subject to standardisation and testing regimes. All our lenses comply with the FDA’s ‘drop ball test’ and comply with ANSI and other international standards authorities.

High contrast Lenses increase resolution, enhance definition and reduce eye strain.

HIGH CONTRAST LENSES

For sports, there are many different factors that come into play which have an effect on the choice of lenses. For skiers and snowboarders, it is often difficult to see contour lines on the snow. For sailors, it can be difficult to distinguish between the blue of the horizon with the blue of the ocean.  For many regions, the overwhelming amount of blue colours in the ocean makes it hard to notice subtle details on the water. 

High contrast lenses give us control over light transmission by reducing blue light and enhancing red, yellow and green light. This fine tuning adds contrast and enables us to see details in or on the water or in the sky that might be missed by the naked eye. A sharpening of visual acuity allows us to see more clearly and react faster to the world changing around us. It also means less eye fatigue in bright conditions as the eye doesn’t need to strain to see details or movement clearly.  This translates into better performance over longer time periods and most importantly,  better eye health.

LENS MATERIALS

We look at the differences between polycarbonate and nylon material.

Polycarbonate

Polycarbonate has been the lens material of choice for action sports for decades for good reason. To this day, it retains the top spot for impact resistance and shatterproof qualities, so this material is highly suited to impact sports like kitesurfing and wakeboarding.

It is a lightweight lens material with a weight of 1.20g/cm³

The scratch resistance of polycarbonate material is medium. 

The refractive index of polycarbonate is 1.58

The Abbe value is 30.

Each lens material has its own characteristics. We measure 5 key lens characteristics on a scale of 1 – 5, with 5 being the best and 1 the poorest.  

• Visual Clarity •

• Scratch Resistance •

• Weight •

• Impact resistance •

• BPA rating •

Each measure is not necessarily equal in importance. They are there as reference points to allow you to consider which of the lenses is suited to you and your needs.

Nylon

 Nylon offers enhanced clarity, lighter weight and better environmental credentials than polycarbonate. The one measure on which nylon is eclipsed by polycarbonate is impact resistance, but marginally so. 

Super-lightweight lens material with a weight of 1.01g/cm³

The scratch resistance of nylon material is medium.

The refractive index of nylon is 1.51

The Abbe value is 52

A QUALITY WATER REPELLENT COATING IS ESSENTIAL FOR MAINTAINING A CLEAR FOCUS

A QUALITY WATER REPELLENT COATING IS ESSENTIAL FOR MAINTAINING A CLEAR FOCUS

HYDROPHOBIC COATING

All of our watersports sunglasses lenses incorporate a hydrophobic and oleophobic coating on both sides of the lenses.

A hydrophobic coating repels water whereas an oleophobic coating repels oils, sweat, dirt and dust. 

The purpose of this coating is to reduce  ‘water-spotting’ which will help keep your vision clear and uninhibited.

As the graphic below shows, the hydrophobic layer repels water droplets by weakening the bond of the water molecules to the lens surface. 

This repellence encourages water droplets to bead together and drop away under gravity or be pushed aside by the force of the wind.

The efficiency of this coating is proportional to the cleanliness of the lens. Regularly cleaning the lenses will ensure maximum hydrophobic performance.

TRI-PEL and RI-PEL COATINGS by ZEISS

TRI-PEL: Created for watersports and used in the TYPHOON, this unique production process from Carl Zeiss Vision combines the outstanding, easy to clean, oil and water repellent features of the Ri-Pel coating, together with the technical performance of the Zeiss Tri-Flection patented mirror series. This compound surface also offers an exceptionally long-lasting anti-smudge mirror treatment.

 

RI-PEL: The Ri-Pel coating is the anti-smudge hydrophobic and oleophobic coating without the Tri-flection mirror coating but which can accommodate alternative mirror coatings such as Flash Pacific Blue or Multilayer Rose Gold.

Tri-Pel™ is a performance mirror that incorporates the most advanced technology of two premium coatings developed by ZEISS laboratories.

Tri-Flection Mirror

  • Anti-smudge and easy to clean technology: the lens is easier to clean than ordinary mirrors.
  • High compatibility: thanks to its light effect, the mirror can be applied on the lens without significantly altering the original lens tint and light transmission.
  • Stylish look:  subtle mirror effect.

+

Ri-Pel Coating

  • Transparent hydrophobic & oleophobic coating: dirt, water, sweat, salt, oil, sunscreen and dust slip off the lens surface easily, ensuring a clear and protected vision.
  • Easy to clean: fingerprints and other contaminates are easily
    removed.
  • Durable and steady performances over time.

POLARISATION

DEALING WITH GLARE

‘Glare’ or reflections of visible light from a surface like water is the loss of visual performance when too much visible light enters the eyes and the eyes are unable to adequately cope with the intensity. In a cloudless sunset, it can be extremely uncomfortable, quickly leading to irritation (redness and dryness) and eye fatigue.

We generally respond to glare by squinting or looking away. This is undesirable for fast moving watersports or if you need to maintain a strong focus. With sunglasses that do not have polarisation, it can still be blinding and this can distract you from what’s going on around you.

POLARISED LENSES WILL REMOVE 99% OF GLARE

POLARISATION

Our polarised lenses filter out 99% of glare. While non-polarised lenses reduce the amount of visible light reaching the eye, they will not have an impact on glare reduction. Polarised lenses strip out 99% of glare and will provide enhanced vision for unmatched clarity and comfort on the water.

WHAT IS POLARISED LIGHT?

Light is comprised of electromagnetic waves and is generally unpolarised. Unpolarised light is the combination of a large number of these waves emitted by atoms at the light source (e.g. the sun) that are orientated in multiple directions. Each atom produces its own wave orientation and the combination of all the waves results in a superposition of waves. Unpolarised light is what is emitted by the sun, and is what we see all around us every day. Light becomes polarised when if reflects off a surface like water or snow. This means that the waves which were formerly orientated in all directions become orientated in two axes – vertically and horizontally. 

The visible light that reflects off the surface of the water is orientated more horizontally than vertically, and it is this horizontally orientated light that causes the uncomfortable glare we perceive. The lens depicted in the image below has a polarisation layer orientated on the Y (vertical) axis. This will strip out any horizontally orientated waves (thus erasing the glare) and allow only vertically orientated light through to the eye.

Abbe Values

The Abbe value is a number given to describe the amount of chromatic aberration* of a lens.

The higher the value, the less aberration there is, which means that the higher the ABBE value, the higher the optical quality.

Chromatic aberration is where colors are incorrectly refracted or ‘dispersed’ by the lens which results in a mismatch at the focal plane. It can be experienced as color fringing or halos.

Nylon scores the highest of the two lens materials with an Abbe value of 52, whereas polycarbonate has an Abbe value of 30. This means that nylon represents a significant improvement over polycarbonate in terms of visual clarity.

Refractive Index

The index of refraction is the measure of how efficiently a lens material bends light. In mathematical terms, the Refractive Index of a lens is the ratio of the speed of light in a vacuum divided by the speed of light in the lens material. The index range is 1.49 to 1.74. 

The abbe value of a lens is inversely proportional to the index of refraction. So a lens with a low abbe value will have a high index of refraction. A lens with a high refractive index will be thinner (and denser) than a lens with a lower refractive index.

Polycarbonate has an index of refraction of 1.58 while nylon scores 1.51.  While polycarbonate is thinner and denser than nylon, it offers less optical quality owing to the inverse relationship of abbe value to refractive index.

BPA Free

BpA is the abbreviation for ‘Bisphenol A’. It is an industrial chemical that is found in polycarbonate plastics and epoxy resins. It is present in food containers and other consumer products and is strongly suspected of influencing hormonal balance by disrupting endocrine. It has been connected to cancer.

There are trace amounts of BpA in polycarbonate lenses.  Several studies show that exposure to BpA is generally through ingestion  and that any exposure through skin contact is negligible. As you are unlikely to be eating your polycarbonate lenses, it presents a negligible risk.

Nylon is 100% BpA free.
