Tokai’s NCC or neutral colour coating is a special coating that dims the vision field by equally cutting out all of the visible light waves. By doing so, there is less change of colours compared to ordinary sunglasses. Taking advantage of this technology, NCC lenses do not alter colours and make vision more natural, comfortable and closer to real life. This is the same technology used for natural density filters in cameras.

In addition, the coating comes with the same scratch resistant, dust proof, stain proof capabilities as the Tokai MSC coating.

NCC is available in four shades: two classic (Black and Light) and two associated with polarizing treatment (Neutral and Deep Sea) to eliminate glare.
