UV protection 100%

UV radiation is invisible radiation that comes from the sun. It can cause eye damage such as sunburn, dry eye and eye diseases such as cataracts. UV protection for sunglasses is especially important in summer and sunshine, but also in winter when sunlight reflects off the silicon of snow and ice.

Protecting your eyes from the sun's UV rays is important, but wearing glasses is often also a matter of fashion. The EU directive requires all sunglasses sold in the EU to have 100% UV protection (UV400), as evidenced by the CE mark on the frame of the sunglasses. CE approval means that Sunglasses meet all EU requirements for sunglasses (EN ISO 12312-1:2013).

Protecting children's eyes is particularly important because the lens of a child's eye allows more UV radiation to pass through than an adult's and the radiation can penetrate the retina, degenerating it. Dear Sunglasses are large and also protect against UV radiation from the side. The UV 100% or UV 400 mark on sunglasses indicates that the glasses completely filter out UV radiation.

CAT rating for sunglasses

The glare protection of sunglasses is an important factor when choosing the right sunglasses. The purpose of glare protection is to filter out excess sunlight and prevent eye fatigue and glare. Glare shields use the CAT (Category) rating, which classifies the light transmission percentage of the lenses. Glare protection and UV protection are two different things. 

• CAT 0 - Image lenses: Sunglasses have clear or light-coloured lenses. They usually resemble spectacles, which is why they are called imagoglasses. Sunglasses These are called lenses and are therefore known as spectacles. They allow 81-100% of the sun's rays to pass through. They do not protect against glare, but they do have UV protection in accordance with the EU directive. 
• CAT 1 - Cloudy weather lens: 44-80% light transmission. These are well suited for cloudy weather with little sunshine. Glasses from have UV protection according to the EU directive
• CAT 2 - Semi cloudy weather lens: Light transmission 19-43%. These lenses are usually used on cloudy or partly cloudy days. 
• CAT 3 - A sunny and clear weather lens: This category of aurora glasses is best for normal use. They filter 9-18% of the light, giving good comfort even on sunny days.
• CAT 4 - Dark lenses: These glasses are usually used on very sunny days or in conditions where extra effective eye protection is needed. The light transmission percentage is only 3-8%. The lens is so dark that these sunglasses should not be used, for example, when driving a car.

The cat-rating of sunglasses should be taken into account, especially on sunny days and in conditions where sunlight is particularly intense. Different cat-rated glasses offer different levels of eye protection and are designed for different conditions. It is important to choose the right cat category to suit your needs and always wear glasses when necessary. Filters that are too weak do not protect the eyes sufficiently from the harmful effects of the sun, and filters that are too strong can interfere with vision and colour rendition.

POLARIZED LENSES

Polarized sunglasses reduce reflections. Reflection is when the sun's rays are reflected into your eyes from water, snow or glass. You won't be completely blinded by the reflection, but you will have to squint your eyes, which will strain them. Polarised sunglasses help you see details more clearly. It can improve performance and prevent accidents. Your eyes will also not get tired as quickly.

HOW DO POLARISED LENSES WORK?

It is important to understand what light is polarised and what is not. When you light a match it emits non-polarised light. The light comes from random angles in all directions.

Polarised light is created when light is reflected from something, like water or the bonnet of a car, and comes horizontally towards you. This horizontal beam of light causes reflection. This reflection can be dangerous, especially when driving a car or walking on snow.
A special chemical is laminated horizontally onto the lenses and makes the lenses polarised. This pattern blocks the light that comes in horizontally and thus prevents reflection. Light only passes through the polarised lenses in one direction, thus making use of only the light coming in vertically.

BENEFITS OF NON-POLARISED LENSES

• Less eye strain - no eye fatigue
• Better and more detailed vision
• Colours appear clearer and brighter
• Safer operation on water, snow and in traffic

POLARIZED LENSES ARE INTENDED FOR:

• For driving - For driving, low winter sun and sudden reflections are no longer a distraction
• For snow - much more pleasant to do winter sports on snow and to walk on a sunny day
• On the water - You can see the surface and contours of the water more clearly. You don't have to squint all the time

Dimensions of sunglasses

To make it easier for you to choose the right size sunglasses, we always indicate the length of the frame, the width of the frame and the height of the lens of our sunglasses according to the model above.

UV protection 100%

UV radiation is the invisible rays that come from the sun. It can cause eye damage such as sunburn, dry eye and eye diseases such as cataracts. UV protection for sunglasses is especially important in summer and sunshine, but also in winter when sunlight reflects off snow and ice. 

Protecting your eyes from the sun's UV rays is important, but wearing glasses is often also a matter of fashion.

Protecting children's eyes is particularly important because the lens of a child's eye allows more UV radiation to pass through it than an adult's and the radiation can penetrate the retina, degenerating it. Good sunglasses are large and also protect against UV radiation from the side. The UV 100% or UV 400 label on sunglasses tells you that the glasses completely filter out UV radiation.

Polarised lens

The polarised lenses in sunglasses are lenses that filter light to prevent reflections and make the view sharper. Polarised lenses are particularly suitable for bright sunshine as they block the reflections of sunlight from water, snow and other reflective surfaces. This makes the view clearer and sharper, which is particularly useful when boating or playing golf, for example.

Polarising lenses are also useful for motorists, as they block reflections from road surfaces and the windscreen of the car, making the view clearer and safer. 

However, polarised lenses are not suitable for all situations. They can interfere with vision, for example when using digital devices. It is therefore important to choose the right lenses to suit your needs and to take into account the conditions in which they will be used.
