All Granite sunglasses comply with CE directive: 89/686/EEG & European standard: EN1836:2005. The sunglasses are categorized according to different filters, depending on how much visible light is filtered (how dark the glass is). The table below indicates at which light strength a certain category of lens is suitable.
The frame item number and the lens filter category number are printed along the inside of the bow. This makes it easy to choose a frame for a specific need.
All Granite sunglasses are grouped according to price. The price group is indicated on the handtag. All glasses have two barcodes on the handtag, one indicating the unique product and one only connected to the price group. Our display racks come with a price group display sign, which simplifies handling the products in the store.
Our retailers have varying needs when it comes to displaying and exposing Granite eyewear. To satisfy these needs, we often create individually tailored solutions. If your store demands specialised exposure solutions, please do not hesitate to contact our head office so that we can find the right solution together.
Granite eyewear is available with several different types of lenses. All of them block ultraviolet UVA and UVB rays. The material used in most of our lenses is shatter-proof acrylic, but we also use unbreakable polycarbonate for some special-purpose frames, particularly for use in sports activities. The most common types of lenses can be used in the following instances:
Gives better contrast in poor light, e.g. dusk, fog and snowfall; a perfect lens for skiing, bicycling and shooting. This lens is also suitable for driving in low visibility conditions.
This lens (known as normal sunglass lens) reduces sunlight considerably and gives real colour rendition. Available in grey, green and brown.
Absorbs horizontal reflexes and glare from water surfaces, wet roads, and snow. Suitable for driving, skiing or sailing.
A normal tinted lens, with a tinted reflective coating on the outside (mirror effect). Reduces sunlight, snow and water glare considerably. Several shades are available, but silver is the most common.The flash lens has a slight mirror effect, not as pronounced as an actual mirror lens.
