Northweek is a popular Spanish brand that mainly focuses on young generations. It combines top-quality materials with original designs and the latest trends. The sunglasses collection is ideal for those who love the sun and fashion and who are not afraid to show their unique style. Northweek Bold Crystal are unisex sunglasses. Sunglasses frame The blue colour of the frame perfectly matches a cool skin tone and light brown, black or light blonde hair. Rectangle sunglasses frames are an ideal choice for those with an oval or round face shape. The frame of the sunglasses is made of high-quality plastic, which offers great durability and comfort. Sunglasses lens The blue lenses enhance contrast and minimize light reflections. For tennis players, the lenses help emphasize the color contrast of the ball against various backgrounds. The lenses are made of plastic which is lightweight and crack-resistant. Polarised lenses offer perfect vision, eliminate unwanted reflections and protect your eyes from ultraviolet radiation. They improve resolution, depth of field and focus. Polarised sunglasses filter out reflected white light, which makes them particularly useful for driving, cycling, skiing and fishing. These lenses are equally fashionable and suitable for everyday wear. Mirrored lenses are characterised by a highly reflective surface, which reduces the amount of light that enters the eye. This feature makes mirrored sunglasses extremely suitable for very bright days or glaring environments like ski slopes. Mirroring provides great visual comfort but can slightly distort colour perception. The shades have UV 400 protection, which provides 100% protection from sunlight. The lenses feature a category 3 sun filter (light transmission 8 – 18% ). They are suitable for intense sun exposure on the beach or in the city. Accessories The cloth supplied is ideal for cleaning and caring for sunglasses. Some models may come with a fabric bag instead of a cloth.
