They include sunglasses and glasses repairing to restore their natural beauty.
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.
Benefits of Saddle Bridge Glasses.
The most common type of plastic bridge is called a saddle bridge. The style is very comfortable because it distributes the weight of the glasses over a larger area rather than focusing on smaller points, like adjustable nose pads. Saddles are known to cost less to repair because they have fewer moving parts and are possible to maintain their fitness. There is now a new saddle bridge-type transparent silicone cushion for a screw-type nose pad. It is made of medical-grade soft silicone. It can be bent and is very soft. To fit the curve of the nose, a plastic frame with a saddle or keyhole bridge can slip off the nose without proper support. Silicone is a soft and elastic material that can be formed according to the contour and shape of the nose.
Is there a standard for lens material selection?
No, again, according to your needs and budget. The materials of lens mainly include glass and resin, among which resin materials are divided into thermoplastic materials and thermosetting materials, respectively represented by PC and CR39. Different from the lens frame, the lens market choice is more uniform. And in recent years, resin lenses do better and better, most people choose thermosetting resin lenses.

Titanium alloys have low thermal elasticity
The thermal conductivity of titanium is about 1/4 of nickel, 1/5 of iron, 1/14 of aluminum, and the thermal conductivity of different titanium alloys is about 50% lower than that of titanium.
The elastic modulus of titanium alloy is about 1/2 that of steel, so its rigidity is poor and is easy to deform, and it is not suitable to make slender rods and thin wall parts. When cutting, the spring back of the processing surface is very large, about 2 ~ 3 times of stainless steel, resulting in severe friction, adhesion, and bonding wear of the knife surface.
TR90 glasses frame
TR90 is not easy to deform and break, and it can withstand high temperatures and strong impacts. In addition, its material is relatively light, so many young people also like such glasses frames.
