A material widely used in plastic frames. Due to its high transparency, acetate provides bright and beautiful lustrous colors.
A light and soft metal with high processability in production. While 40% lighter than titanium, it is inferior in terms of strength and corrosion resistance. Used for many years in the manufacturing of temples.
A frame shape used by the US air force that has become an eyewear icon.
The width / horizontal measurement of a lens.
Anti-Reflective coating. A coating that eliminates the reflection from the concave side of the lens, and protects it from scratches and/or adherence of dirt.
A titanium alloy consisting of titanium, vanadium and aluminum. Stronger than pure titanium, but just as lightweight and corrosion-resistant. Due to its elastic properties, even a thinly designed beta titanium frame retains its strength.
The part between the two rims, which extends across the nose.
The depth / vertical measurement of the lens.
A lens with two focal areas: typically with a farsighted correction on top and nearsighted area on the bottom of the lens.
It is used in the body of racing cars, car fenders, electric machine devices, and, to a degree, in eyewear. It is extremely abrasion-, heat-, and acid-resistant.
A manufacturing process mainly used to create end pieces or ornamental parts. A processing method in which beryllium copper or titanium is melted then cooled in a mold to form the parts.
A technique used to decorate certain details of the frame with resin. Its stereoscopic and transparent effect creates a decorative and high-value frame.
A square shape transformed from the aviator.
A retro frame style in which the outer edges of the almond shaped lenses are upswept. Also called the 'Monroe style' as the style was recognizably worn by Marilyn Monroe in a film.
A commonly used lens made of a resin called CR 39 with a wide variety of colors ranging from full colors to gradated colors.
A very light aluminum alloy, inferior to titanium in strength and corrosion-resistance, but lighter in weight.
DBL = Distance Between the Lenses
Also called the bridge size, it refers to the minimum horizontal distance between the lenses.
A new titanium alloy that offers high flexibility and memory function, and is nickel free. Patented by CHARMANT Group.
A coating technique that electrically applies colored resin onto the surface of a frame. It embellishes the frame while also making it corrosion-resistant.
A secondary surface treatment of thin, highly adhesive colored film. Mostly used for the rim color to enhance embellishment. It provides a lighter expression than cloisonné.
The end of the temple that rests over the ear.
The portion of the frame that extends outwards from the front piece and connects to the hinges.
ED = Effective Diameter.
It indicates the minimum size/diameter of the lens to be used.
