Anti UV CUT Lens

Protecting your eyes from ultraviolet radiation.

The ultraviolet radiation emitted from the sun not only damaged our skin but also our eyes as well. Our all PETROID lenses cut 99.9% of UV rays.

Type of UV RaysTypes  of UV rays

When referring to the wavelength of radiation we distinguish between UV-A, UV-B and UV-C, while the A and B type radiation are able to reach the earth surface. A large quantity of the very dangerous UV-B is absorbed be the surface if the eye consisting of the cornea and the crystalline lens where the rays cause serious damage. UV-A , which reaches the earth surface in the largest quantity, penetrates deep into the eye. Consequently, sunbathing for an extended amount of time can increase the risk to youth health.

Polarized Lens

Prevents glare and makes your vision clearer
Polarized lenses have a special filter function which cuts out diffuse reflected rays from various objects such as cars, buildings, road and water surfaces, in order to make your vision clearer.

Comparison Polarized lens

Worldwide SWANS has been the first manufacturer of polarized lenses to incorporate polarized films into the polycarbonate lens by the method of molding technology. These lenses are resistant to impacts and scratches while having an exceptional high optical precision without any distortion.

Polarization degree : > 90% .Visible light transmission rate: approx. 10 – 40%


POLA has a significantly higher polarization ratio. As a result, it is very effective against strong sunlight, even when used on a bright and sunny day.

Polarization degree :> 90% Visible light transmission rate: approx. 10 – 30%

pola light

With approximately 60% polarization, POLA LIGHT has a significantly lower polarization ratio compared to the normal POLA. The bigger amount of
light transmitted through the lens makes vision brighter. Used on cloudy or rainy days, POLA LIGHT provides enough brightness and contrast for a clear vision.

Polarization degree : > 60%. Visible light transmission rate :approx. 50%





New technology lens that is gentle to your eyes
Even if it is considered as visible light, blue light has a bad influence on the eyes. Now, there is a lens which reduces the amount of blue light exposure: the FULLERENE lens. Using lens, your vision becomes clear and comforting

Fullerene Lens

What is Fullerene?

Fullerene is a new nanocarbon material consisting of 60-70 carbon atoms arranged like soccer ball. In 2009 YAMAMOTO KOGAKU accomplished in combining this new material to the PETROID lens creating a lens which reduces only blue light.

Protecting the eye from strong sunlight and glareMirror Coat Lens
The surface of mirror lenses is coated with a reflecting membrane, which is suited for cutting down strong sunlight and glare. By controlling the coating film and the lens base, you can adjust the colour and the amount of light that enters the lens. The wearer is free to choose the most suitable lens colour for the particular sporting occasion. Another benefit of mirror coating is that outside observers athletes to predict your actions.


Claritex Interior/Exterior
Preventing water and dust from obscuring your visionClaritex Coat
The CLARITEX COAT is SWANS’ new state of art water and dust repellent coating. It repels water for a clearer vision in wet conditions. Further, the CLARITEX anti-scratch coating keeps your lens looking brand new year after year. The DOUBLE CLARITEX COAT protects against splashes of water and sweat, which usually linger on the back side of the lens. This gives a clearer view to the wearer.


Double CoatClear vision without distracting reflectionsDouble Coating
Being applied on the back side of the lens, the MULTI-COAT keeps your vision clear by preventing reflected light that comes from behind you. If you choose the DOUBLE MULTI-COAT, the inner surface coating will prevent reflection, while the outer surface coating stops glare from entering the lens. For the usage of MULTI-COAT lenses we recommend light coloured lenses, which are the most comfortable colouring.



Lenses adapt colour according to UV radiation
This special lens changes its colour to eliminate UV radiation by responding to the amount of UV passing through it. When a large amount of UV radiation enters the lens, the colour changes from clear to smoke. However, when only a small amount of UV enters, the lens becomes clear again.
