Charmant glasses
Japanese Charmant Group is one of the world's famous eyewear manufacturing enterprises. Since its inception in 1956, it has always been the leader of cutting-edge technology in the field of eyewear manufacturing. Charmant is a global titanium expert, and now the domestic market has launched 7 series of titanium, like Z titanium, etc., to meet the Chinese consumers’ pursuit of all ages for high-quality glasses and more comfortable glasses.
Among them, EX titanium is a patent developed by Charmant Group. Compared with common memory titanium, EX titanium has a more stable memory function and a more diversified design.The frame price of Charmant glasses is 1000 yuan above basically, from 1000 to 4000.
Why do spectacle frames rust?
Before solving this problem, we can first understand the causes of rust spots on the frames and skin allergies due to rust spots. Many alloy products in daily life contain nickel, and direct contact with the skin will cause allergies to sensitive people. The temples and nose pads are the parts that contact the skin with a large area, especially the outer surface of the metal frame and the interior of metal containing a large amount of nickel. Through contact with the skin and erosion of sweat, the appearance of rust spots and skin allergies are caused. Once allergy occurs, it will cause contact dermatitides such as redness, swelling, itching, and yellow water on the surrounding skin.

How do you identify the refractive index of lens?
In reality, this problem is often a problem for optical shop practitioners, sometimes they worry about whether the manufacturer's lenses match the nominal value of the refractive index. We need a prop, and that's the camber. Because it can be used to measure the strength of the lens. The luminosity of the lens can be calculated by subtracting the curvature of the inner and outer surfaces of the lens. The curvature difference of a lens of the same luminosity is inversely proportional to the refractive index, that is, a lens with a higher refractive index only needs a smaller curvature difference to achieve the same luminosity.
Disadvantages of glasses
They can distort vision, especially at the edges of lenses if you have strong prescriptions or astigmatism. Some people have trouble adjusting to progressive lenses. These lenses fog up and splash in the rain. Due to the limitation of the frame itself and the effect of the prism effect in the peripheral part of the glasses, the wearer can see a relatively narrow field of vision.
Lunor
Lunor glasses integrate classical aesthetics into modern design and are compared to modern antiques. Lunor glasses insist on handmade, and some styles need 200 processes to complete. In addition to the fine processing of the frame, in Lunor, each glasses box made of wood or sheepskin was made by hand in a German factory, making the whole product like a work of art and pretty valuable.
What are nose pads?
Nose pads include stipule stalk, stipule boxes, and stipules. The stipules are in direct contact with the nose and play a role in supporting and stabilizing the frame. Certain molded plastic frames may not have stipules and stipule boxes, and the stipules are connected to the mirror ring.
In fact, when designing different materials and different styles, the designer will judge whether nose pads are needed according to the comfort and aesthetics of the glasses. Generally, metal frames are equipped with nose pads, and the nose pads are movable in order to adapt to various nose shapes. Metal frames with nose pads can prevent some people's skin from being allergic to metal. On the other hand, metal looks more rigid and business, and adding nose pads is more beautiful and comfortable. Most glasses without nose pads are sheet-framed glasses. The sheet material is relatively light and non-allergenic. In terms of aesthetics and comfort, no nose pads are more suitable.
