Choose the right category
Design and fit may be important when choosing sunglasses, but more importantly, the sunglasses protect your eyes from harmful rays. This requires the sunglasses to have a sun filter. The strength of the filter determines how strong the sun it protects against and determines which category the glasses fall into:
- Category 0 is for cloudy weather.
- Category 1 is too partly cloudy.
- Category 2 is for normal sun.
- Category 3 is for strong sun.
Category 4 is for high mountains and by the sea. Sunglasses with category 4 protection are not suitable if you are going to drive.
Requirements for sunglasses
- All sunglasses sold must include information about the protection category of the glasses and how strong the light they protect against.
- Sunglasses must be CE marked and information about who the manufacturer is must be included.
- If the sunglasses can be damaged by cleaning products, care information must be included in Norwegian where this is explained.
