The Laceto NASH polarised sunglasses have a plastic frame with a matte finish in black which is perfectly complemented by orange details. The polarised smoky lenses have a filter category of 3 which is suitable for casual wear during sunny summer days. A filter in this category transmits only 8-18% of sunlight. The glasses have a polarising treatment and filter the reflected sunlight which will be appreciated, for example, by drivers in winter or after rain.
