What are your glasses made of?
We use three different materials for our frames:
TR-90: It is a type of nylon (plastic) material, it can be found with a soft or rubbery texture or a strong, plastic-type texture. They are very hard, but flexible.
Polycarbonate (Plastic): Polycarbonate is a naturally transparent amorphous thermoplastic. It also has a very good heat resistance and can be combined with flame retardant materials without significant material degradation.
Metal Alloy: Alloys are metals with other elements added to improve properties like strength or stiffness. This alloy is strong and can also be welded, brazed, and soldered.
