Cellulose acetate is a plant-based plastic obtained from cellulose (which is an organic compound extracted from cotton and wood fibres). It is particularly well-suited for use in the manufacture of eyeglasses because it is lightweight, durable, and flexible as well as being hypo-allergenic. 
We only use Japanese acetate…. Here’s why!
Extremely important characteristics of Japanese acetate:
  • its long-term stability, due to the limited use of chemical products in the creation of the colours;
  • the sheen, depth, and richness of the colours as a result of over 100 hours of tumbling using specific materials such as fragments of bamboo, wood, ceramic, plastic, and corn. After which the hand polishing of every single piece is fundamental.
Titanium is a metal known for its resistance to corrosion and for its high mechanical strength to weight ratio.
It is lightweight, approximately 45% lighter than steel, hard, and long lasting. Being biocompatible it is widely used in the medical field: surgical tools, prostheses, dental implants...
Due to its physical characteristics, it is also used in the fields of aviation, space, defence, and athletics.
To make it more flexible, titanium is combined with other materials to create a beta-titanium alloy, primarily used in the manufacture of temples for eyeglasses.
All of the characteristics mentioned above, as well as the fact that titanium is hypo-allergenic and nickel-free, make it the perfect material for the manufacture of metal-frame glasses.
The lenses used in NOBìKA sunglasses are made from organic material (CR39) and feature the following characteristics:
Anti-reflective coating - Mirroring - Hardening
These processes guarantee excellent and clear vision, optimum protection from sunlight and more effective resistance to scratches. If the glasses read "Polarized", the lens is polarized, which also eliminates reflections and increases perception contrast. The construction of this type of lens is technologically very advanced. The polarizing film is "sandwiched" inside the lens. This process protects the film and ensures longer life.
NOBìKA eyewear is made to be treasured and loved, ensuring that its prestigious characteristics and comfort remain. Two simple rules :
- Clean regularly with running water and a neutral detergent then dry with a soft cloth
- Avoid the use of solvents and cleaning chemicals which could compromise the glasses' functionality.
